• How can I encode a Perl string so I can put it into an XML document?

  - by Sho Minamimoto

  I'm not too fluent with the perl XML libraries (actually, I really suck at understanding encoding in general), all I'm doing is taking a string that possibly has characters such as "à" and putting it in an XML file, but when I open the file, I get an encoding error at the line containing such a character. So I just need a lightweight way to take a string and encode it for XML.

• Bizarre Escape Character Question

  - by William Calleja

  I have the following c# code embedded in a literal <% %> of a c# asp.net page string commandString = "SELECT tblData.Content " + "FROM tblData " + "WHERE (tblData.ref = N\'%"+myCurrentREF+"%\')"; This is breaking my code since it apparently cannot use the \' escape character. Why is it so? other escape characters like \" are working so why isn't \' working?

• PHP - ___ encoding to UTF-8 - is there an end-all solution?

  - by Kerry

  I've looked across the web, I've looked through SO, through PHP documentation and more. It seems like a ridiculous problem not to have a standard solution to. If you get an unknown character set, and it has strange characters (like english quotes), is there a standard way to convert them to UTF-8? I've seen many messy solutions using a plethora of functions and checking and none of them are definitely going to work. Has anyone come up with their own function or a solution that always works?

• How to generate real UTF-8 XML with grails without the escape characters?

  - by AngeDeLaMort

  I have been wondering why when I set the encoding to UTF-8 and rendering the XML it replace the extended characters by escape characters (or character reference) like &#x2019; instead of '? I'm using the Render method render(contentType:"text/xml", encoding:"UTF-8") {...} with a proper header render(contentType:"text/xml", encoding:"UTF-8", text:"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n") Any idea if there is a way to write it properly? Thanks.

• json specifies "any UNICODE character"?

  - by bukzor

  Maybe this is just my unfamiliarity with unicode, so please correct me if I'm mistaken. Looking at http://json.org/, the spec says that a string can include "any UNICODE character", but this confuses me. JSON is a communication format correct? At the core of it, everything must translate down to bytes. In contrast, UNICODE is a logical format and must be encoded to be able to transmit it, right? So what did they mean there?
