  • weird characters in HTML email

    - by sims
    Hi stackers! I'm reading email from a maildir and some emails have weird sets of characters in them: =3D =09 I think =3D is = and =09 is a space. There are some others, but I'm not sure: =E2 =80 =93 Does anyone know what these are and what encoding issues I'm dealing with here? BTW, I tried fetching these email via POP3 and it's the same thing. The reason I'm posting this on SO is not because I'm using a regular mail client to read the data. I'm reading via PHP out of maildir files. Perhaps a regular email client would detect what encoding this is and deal with it. Thanks!

  • Caesar Cipher in Java (Spanish Characters)

    - by Rodolfo
    I've reading this question, and I was wondering if Is there any way to consider the whole range of characters? For example, "á", "é", "ö", "ñ", and not consider " " (the [Space])? (For example, my String is "Hello World", and the standard result is "Khoor#Zruog"; I want to erase that "#", so the result would be "KhoorZruog") I'm sure my answer is in this piece of code: if (c >= 32 && c <= 127) { // Change base to make life easier, and use an // int explicitly to avoid worrying... cast later int x = c - 32; x = (x + shift) % 96; chars[i] = (char) (x + 32); } But I've tried some things, and it didn't work.

  • MySQL update error when special characters are used

    - by Katy
    Hi All, I was wondering if anyone had come across this one before. I have a customer who uses special characters in their product description field. Updating to a MySQL database works fine if we use their HTML equivalents but it fails if the character itself is used (copied from either character map or Word I would assume). Has anyone seen this behaviour before? The character in question in this case is ø - and we can't seem to do a replace on it (in ASP at least) as the character comes though to the SQL string as a "?". Any suggestions much appreciated - thanks!

  • Generating the permutations from a number of Characters

    - by adam08
    I'm working on a predictive text solution and have all the words being retrieved from a Trie based on input for a certain string of characters, i.e. "at" will give all words formed with "at" as a prefix. The problem that I have now, is that we are also supposed to return all other possibilities from pressing these 2 buttons, Button 2 and button 8 on the mobile phone, which would also give words formed with, "au, av, bt, bu, bv, ct, cu, cv" (most of which won't have any actual words. Can anyone suggest a solution and how I would go about doing this for calculating the different permutations? (at the moment, I'm prompting the user to enter the prefix (not using a GUI right now)

  • Characters in usernames that cause trouble

    - by acidzombie24
    I am testing out security and reliability issues on my site. I have made \n and \r illegal. I created a user with null in the name which caused my PM system to not message the user. However \b worked and \t didnt allow copy/paste to work correctly. The browser (firefox which i am testing with) copied the tab as a single space causing the name not to be the same thus not recognizing the username. Since i cant copy paste easily i'll probably disallow it. \f works as well although i do see a symbol in the title but nowhere else because of the \f. What else should i try? It appears 0-31 127-159 (i dont understand this range) are illegal. What characters in legal range might i want to disallow? I heard there was a 0 width character space. That may be something i want to disallow? What else is there?

  • Illegal characters for SharePoint 2010 Content Type name

    - by Kelly Jones
    Quick tip: you can’t include a backslash in the name of the SharePoint 2010 Content Type.  In fact, there are several illegal characters:  \  / : * ? " # % < > { } | ~ & , two consecutive periods (..), or special characters such as a tab. What, you didn’t know that after entering one of these characters in the name?  Is it because you saw this screen: Oh, that’s right….you need to turn off custom errors in the layouts folder…See this blog post for details and you’ll also need to turn off for the web application. Once you do that, you’ll see this: I wonder why the SharePoint team just doesn’t let the user know that the content type name contains illegal characters before the user hits the create button. Here’s a copy of the complete error (for the search engines): Server Error in '/' Application. -------------------------------------------------------------------------------- The content type name 'asdfadsf\asdfasf' cannot contain: \  / : * ?

  • How do I correctly display special characters in my Firefox browser?

    - by BrianH
    (Firefox 3.6.13 on Windows XP) Every once in a while I notice an odd character on certain web pages when browsing the web. It is a outline of a box with a 4-digit number inside. And example of a page that has these characters is: http://aws.amazon.com/ec2/#highlights After each section heading (Elastic, Completely Controlled, ...) I see a box with the number "0096" inside. I looked at the cached version on Google, and google has &ndash; in it's place, so I'm guessing I should be seeing a dash there instead of the box with the numbers in it. I have tried changing the character encoding in Firefox but haven't been able to find one that shows these characters correctly. Is there a way to allow Firefox to view these characters? Thanks in advance!

  • Regex, encoding, and characters that look a like

    - by hack.augusto
    First, a brief example, let's say I have this "/[0-9]{2}°/" regex and this text "24º". The text won't match, obviusly ... (?) really, it depends on the character encoding. Here is my problem, I do not have control on which chars the user uses, so, I need to cover all possibilities in the regex /[0-9]{2}[°º]/, or even better, assure that the text has only the chars I'm expecting °. But I can't just remove the unknow chars otherwise the regex won't work, I need to change it to the chars that looks like it and I'm expecting. I have done this through a little function that maps the "look like" to "what I expect" and change it, the problem is, I have not covered all possibilities, for example, today I found a new "-", now we got three of them, just like latex =D - -- --- ,cool , but the regex didn't work. Does anyone knows how I might solve this?

  • Freely available dictionary data for Chinese, Japanese, CJK characters

    - by devio
    I am developing an online CJK character dictionary application, and already found the following databases: Unicode Unihan Database Jim Breen's JMDict and KanjiDic CEDict HanDeDict As I am looking for more data, web searches often lead me to online dictionaries, but not the data itself, using the same sources over again. If you know of any CJK-relevant downloadable dictionaries, please add them.

  • Unicode replacement characters for text matching

    - by Christian Harms
    I have some fun with unicode text sources (all correct encodet) and I want to match names. The classic problem, one source comes correctly, an other has more flatten names: "Elblag" vs. "Elblag" (see the character a) How can I "flatten" a, á, â or à to a for better matching? Are there unicode to ascii- matching tables?

  • .aspx character coding

    - by kwek-kwek
    I am having an problem. First time working with a windows server, do you know if there is any problem in character coding? My document is set to content="text/html; charset=UTF-8" but it's giving me funny words... you can check it here. This site is a pure HTML with few includes but anything else is just HTML. I can convert them to HTML entities but that is basically wasting my time. I never had this problem with any website I did except for this. Some others said "The problems seems to be that you have converted the text into utf-8 twice.". But how would Coverted it twice since dreamweaver should convert it for me but in this case it doesn't.

    - by UnLoCo
    Hello i followed this snippet http://bytes.com/topic/javascript/answers/504399-get-all-text-nodes var xPathResult = document.evaluate( './/text()[normalize-space(.) != ""]', document.body, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null ); for (var i = 0, l = xPathResult.snapshotLength; i < l; i++) { var textNode = xPathResult.snapshotItem(i); textNode.data = textNode.data.replace(/somePattern/g, 'replacement'); } i want to replace certain patterns like for example |12| with a corresponding emoticon ! but when i do textNode.data.replace("|12|",'<.img src="favicon.ico"/>'); for example the text show is ..<.img src="favicon.ico"/>.. as i inspect the html i find that <.img src="favicon.ico"/> became escaped to &lt;img src="favicon.ico"/&gt; is it possible to prevent this and to let the image show ??

    I have a nodejs TCP server and a client. Basic network communication happens. Client sends "data + STX_CHARACTER + data + ETX_CHARACTER" (just an example). How do I split the string using the STX Control Character as a delimiter or how do I reference the character at all in Javascript.

  • PHP unserialize fails with non-encoded characters?

    - by FFish
    $ser = 'a:2:{i:0;s:5:"héllö";i:1;s:5:"wörld";}'; // fails $ser2 = 'a:2:{i:0;s:5:"hello";i:1;s:5:"world";}'; // works $out = unserialize($ser); $out2 = unserialize($ser2); print_r($out); print_r($out2); echo "<hr>"; But why? Should I encode before serialzing than? How? I am using Javascript to write the serialized string to a hidden field, than PHP's $_POST In JS I have something like: function writeImgData() { var caption_arr = new Array(); $('.album img').each(function(index) { caption_arr.push($(this).attr('alt')); }); $("#hidden-field").attr("value", serializeArray(caption_arr)); };

  • Criminals and Other Illegal Characters

    - by Most Valuable Yak (Rob Volk)
    SQLTeam's favorite Slovenian blogger Mladen (b | t) had an interesting question on Twitter: http://www.twitter.com/MladenPrajdic/status/347057950470307841 I liked Kendal Van Dyke's (b | t) reply: http://twitter.com/SQLDBA/status/347058908801667072 And he was right!  This is one of those pretty-useless-but-sounds-interesting propositions that I've based all my presentations on, and most of my blog posts. If you read all the replies you'll see a lot of good suggestions.  I particularly like Aaron Bertrand's (b | t) idea of going into the Unicode character set, since there are over 65,000 characters available.  But how to find an illegal character?  Detective work? I'm working on the premise that if SQL Server will reject it as a name it would throw an error.  So all we have to do is generate all Unicode characters, rename a database with that character, and catch any errors. It turns out that dynamic SQL can lend a hand here: IF DB_ID(N'a') IS NULL CREATE DATABASE [a]; DECLARE @c INT=1, @sql NVARCHAR(MAX)=N'', @err NVARCHAR(MAX)=N''; WHILE @c<65536 BEGIN BEGIN TRY SET @sql=N'alter database ' + QUOTENAME(CASE WHEN @c=1 THEN N'a' ELSE NCHAR(@c-1) END) + N' modify name=' + QUOTENAME(NCHAR(@c)); RAISERROR(N'*** Trying %d',10,1,@c) WITH NOWAIT; EXEC(@sql); SET @c+=1; END TRY BEGIN CATCH SET @err=ERROR_MESSAGE(); RAISERROR(N'Ooops - %d - %s',10,1,@c,@err) WITH NOWAIT; BREAK; END CATCH END SET @sql=N'alter database ' + QUOTENAME(NCHAR(@c-1)) + N' modify name=[a]'; EXEC(@sql); The script creates a dummy database "a" if it doesn't already exist, and only tests single characters as a database name.  If you have databases with single character names then you shouldn't run this on that server. It takes a few minutes to run, but if you do you'll see that no errors are thrown for any of the characters.  It seems that SQL Server will accept any character, no matter where they're from.  (Well, there's one, but I won't tell you which. Actually there's 2, but one of them requires some deep existential thinking.) The output is also interesting, as quite a few codes do some weird things there.  I'm pretty sure it's due to the font used in SSMS for the messages output window, not all characters are available.  If you run it using the SQLCMD utility, and use the -o switch to output to a file, and -u for Unicode output, you can open the file in Notepad or another text editor and see the whole thing. I'm not sure what character I'd recommend to answer Mladen's question.  I think the standard tab (ASCII 9) is fine.  There's also several specific separator characters in the original ASCII character set (decimal 28-31). But of all the choices available in Unicode whitespace, I think my favorite would be the Mongolian Vowel Separator.  Or maybe the zero-width space. (that'll be fun to print!)  And since this is Mladen we're talking about, here's a good selection of "intriguing" characters he could use.

  • Error with TextMate 2 --shell-escape and gnuplot 10.8.2

    - by Manuel
    I have had TM 1.X since a long time ago, but a week ago I updated my system to Mountain Lion 10.8.2 and installed TM2. The problem is that I write with LaTeX, and sometimes I use gnuplot for the graphs (I installed gnuplot with macports). But now it doesn't work because the --shell-escape doesn't work, this is the error message I get: Package pgfplots Error: Sorry, the gnuplot-result file '"untitled 2.pgf-plot.table"' could not be found. Maybe you need to enable the shell-escape feature? For pdflatex, this is ' pdflatex -shell-escape'. You can also invoke ' gnuplot .gnuplot' manually on the respective gnuplot file.. And then, looking around I discovered that it's not just gnuplot but everything which needs --shell-escape. Question What happened? How can I get TM have the correct rights so this works? It worked right in Snow Leopard with TM 1.5.
