  • Harmonizing Character Encoding Between Imported Data and MySQL

    MySQL's Latin-1 default encoding combined with MySQL 4.1.12's (or greater) UTF8 encoding allows the maximum number of characters codes, however incoming data with different character encoding can still present problems. Rob Gravelle shows you how to avoid problems before a lot of work is required to undo the damage.

  • Read All Text from Textfile with Encoding in Windows RT

    - by jdanforth
    A simple extension for reading all text from a text file in WinRT with a specific encoding, made as an extension to StorageFile: public static class StorageFileExtensions {     async public static Task<string> ReadAllTextAsync(this StorageFile storageFile)     {         var buffer = await FileIO.ReadBufferAsync(storageFile);         var fileData = buffer.ToArray();         var encoding = Encoding.GetEncoding("Windows-1252");         var text = encoding.GetString(fileData, 0, fileData.Length);         return text;     } }

  • What c# equivalent encoding does Python's hash.digest() use ?

    - by The_AlienCoder
    I am trying to port a python program to c#. Here is the line that's supposed to be a walkthrough but is currently tormenting me: hash = hashlib.md5(inputstring).digest() After generating a similar MD5 hash in c# It is absolutely vital that I create a similar hash string as the original python program or my whole application will fail. My confusion lies in which encoding to use when converting to string in c# i.e ?Encoding enc = new ?Encoding(); string Hash =enc.GetString(HashBytes); //HashBytes is my generated hash Because I am unable to create two similar hashes when using Encoding.Default i.e string Hash = Encoding.Default.GetString(HashBytes); So I'm thinking knowing the deafult hash.digest() encoding for python would help

  • how to know which special character is there in a file?

    - by Pangea
    My app needs to process text files during a batch process. Occassionally I receive a file with some special character at the end of the file. I am not sure what that special character is. Is there anyway I can find what that character is so that I can tell the other team which is producing that file. I have used mozilla's library to guess the file encoding and it says UTF-8.

  • Encoding Special Characters For Outlook HTML Email

    - by n0chi
    I have an asp.net / C# page which takes a comment, and then emails that comment. Sometimes when the user enters "&" in the comment, the comment is being truncated. So for example if the comment is "test & test" the email only sends out "test ". I have tried HttpUtility.HtmlEncode - but it looks like the issue is on the outlook side and not on the C# side.

  • Rle Encoding...What's the wrong?

    - by FILIaS
    I'm trying to make a Rle Encoder Programme.I read the way it works on notes on net. And i tried to fix my code! Regardless I think that the structure and logic of code are right,the code doesnt work! It appears some strange 'Z' as it runs. I really cant find what;s wrong! Could u please give me a piece of advice? Thanx in advance... #include <stdio.h> int main() { int count; unsigned char currChar,prevChar=EOF; while(currChar=getchar() != EOF) { if ( ( (currChar='A')&&(currChar='Z') ) || ( (currChar='a')&&(currChar='z') ) ) { printf("%c",currChar); if(prevChar==currChar) { count=0; currChar=getchar(); while(currChar!='EOF') { if (currChar==prevChar) count++; else { if(count<=9) printf("%d%c",count,prevChar); else { printf("%d%c",reverse(count),prevChar); } prevChar=currChar; break; } } } else prevChar=currChar; if(currChar=='EOF') { printf("%d",count); break; } } else { printf("Error Message:Only characters are accepted! Please try again! False input!"); break; } } return 0; } int reverse(int x) { int piliko,ypoloipo,r=0; x=(x<0)?-x:x; while (x>0) { ypoloipo=x%10; piliko=x/10; r=10*r+ypoloipo; x=piliko; } printf("%d",r); return 0; }

  • Encoding a email address that can be used as part of a URL in codeigniter

    - by freedayum
    Is there a way to encode a email address that can be used as a part of a url in codeigniter?. I need to decode back the email address from the url. What I am trying to do is just a -forgotten password recovery- thing. I send a confirmation link to the user's email address, the link needs to be like ../encodedEmail/forgottenPasswordCode (with the forgottenPasswordCode updated in the db for the user with the submitted email). When the user visits that link, I decode the email(if the email - forgottenPasswordCode pair is in the table), i allow them to reset their password (and i reset forgottenPasswordCode back to null). I could just do a loop -checking the table with a select query- (or) -set that forgottenPasswordCode column unique, so i keep generating on a insert failure(would that be a lot faster ?)- until I generate a forgottenPasswordCode that doesn't already exist in the table. But the guy I do this for would not accept it this way:). He wants the checking be done with the user's email, he thinks its much faster. I am working with codeigniter, I used its encode() function, it seems to produce characters like '-slashes-' at times that breaks the encoded-email-string. Any other ideas?

  • Getting started with character and text processing (encoding, regular expressions)

    - by TK
    I'd like to learn foundations of encodings, characters and text. Understanding these is important for dealing with a large set of text whether that are log files or text source for building algorithms for collective intelligence. My current knowledge is pretty basic: something like "As long as I use UTF-8, I'm okay." I don't say I need to learn about advanced topics right away. But I need to know: Bit and bytes level knowledge of encodings. Characters and alphabets not used in English. Multi-byte encodings. (I understand some Chinese and Japanese. And parsing them is important.) Regular expressions. Algorithm for text processing. Parsing natural languages. I also need an understanding of mathematics and corpus linguistics. The current and future web (semantic, intelligent, real-time web) needs processing, parsing and analyzing large text. I'm looking for some resources (maybe books?) that get me started with some of the bullets. (I find many helpful discussion on regular expressions here on Stack Overflow. So, you don't need to suggest resources on that topic.)

  • Character Encoding problem?

    - by JasonS
    Hi, In my mysql database I have the following information in a page name field. ç,Ç,ö,Ö,ü,Ü,i,I,s,S,g,G If I do a phpmyadmin dump the above is exported. I am using a different php script and instead of the above I am getting this. "\303\247,\303\207,\303\266,\303\226,\303\274,\303\234,\304\261,\304\260,\305\237,\305\236,\304\237,\304\236" This is the snippet which is generating the output. $data_sql = "SELECT * FROM ".$table_name; $data_res = @mysql_query($data_sql); while($data_row = @mysql_fetch_array($data_res,MYSQL_NUM)) { print_r($data_row); } How can I modify this to make sure that the data is correct? Is some sort of php function required? Do I need to do something to the file? Any advice is much appreciated.

  • Text encoding in HTML text fields

    - by joe
    I have a site up that has a form on it. The form POSTs to a php script which then inserts the data into my database. The page has a charset=UTF-8 attribute in the <meta> tag, and the database is setup to use UTF-8. However, when I copy and paste characters from MS Word into the field, the output is messed up. For example, the quotes in I am using "Microsoft Word" '''' become I am using “Microsoft Word†???? in the database. Anyone have any idea why this might occur?

  • Encoding / Error Correction Challenge

    - by emi1faber
    Is it mathematically feasible to encode and initial 4 byte message into 8 bytes and if one of the 8 bytes is completely dropped and another is wrong to reconstruct the initial 4 byte message? There would be no way to retransmit nor would the location of the dropped byte be known. If one uses Reed Solomon error correction with 4 "parity" bytes tacked on to the end of the 4 "data" bytes, such as DDDDPPPP, and you end up with DDDEPPP (where E is an error) and a parity byte has been dropped, I don't believe there's a way to reconstruct the initial message (although correct me if I am wrong)... What about multiplying (or performing another mathematical operation) the initial 4 byte message by a constant, then utilizing properties of an inverse mathematical operation to determine what byte was dropped. Or, impose some constraints on the structure of the message so every other byte needs to be odd and the others need to be even. Alternatively, instead of bytes, it could also be 4 decimal digits encoded in some fashion into 8 decimal digits where errors could be detected & corrected under the same circumstances mentioned above - no retransmission and the location of the dropped byte is not known. I'm looking for any crazy ideas anyone might have... Any ideas out there?

  • UriBuilder incorrectly encoding Query Parameters value ?

    - by Fred
    Lets consider the following code sample where a path and single parameter are encoded... Parameter name: "param" Parameter value: "foo/bar?aaa=bbb&ccc=ddd" (happens to be a url with query parameters) String test = UriBuilder.fromPath("https://dummy.com"). queryParam("param", "foo/bar?aaa=bbb&ccc=ddd"). build().toURL().toString(); The encoded URL string returned is: "https://dummy.com?param=foo/bar?aaa%3Dbbb&ccc%3Dddd" Is this correct ? Should not the character "&" (and may be even "?") be encoded in the parameter value string ? Would not the URL produced be interpreted as follow: One first parameter, name="param", value = "ar?aaa%3Dbbb" followed by a second parameter, name="ccc%3Dddd", without value.

  • Encoding MySQL text fields into UTF-8 text files - problems with special characters

    - by Matt Andrews
    I'm writing a php script to export MySQL database rows into a .txt file formatted for Adobe InDesign's internal markup. Exports work, but when I encounter special characters like é or umlauts, I get weird symbols (eg Chloë Hanslip instead of Chloë Hanslip). Rather than run a search and replace for every possible weird character, I need a better method. I've checked that when the text hits the database, it's saved properly - in the database I see the special characters. My export code basically runs some regular expressions to put in the InDesign code tags, and I'm left with the weird symbols. If I just output the text to the browser (rather than prompt for a text file download), it displays properly. When I save the file I use this code: header("Content-disposition: attachment; filename=test.txt"); header("Content-Type: text/plain; charset=utf-8"); I've tried various combinations of utf8_encode() and iconv() to no avail. Can anybody point me in the right direction here?

  • [Cocoa] NSTask string encoding problem

    - by ryyst
    Hi, In my program, I'm grep-ing via NSTask. For some reason, sometimes I would get no results (even though the code was apparently the same as the command run from the CLI which worked just fine), so I checked through my code and found, in Apple's documentation, that when adding arguments to an NSTask object, "the NSTask object converts both path and the strings in arguments to appropriate C-style strings (using fileSystemRepresentation) before passing them to the task via argv[]" (snip). The problem is that I might grep terms like "Río Gallegos". Sadly (as I checked with fileSystemRepresentation), that undergoes the conversion and turns out to be "RiÃÅo Gallegos". How can I solve this? -- Ry
