#11034: AJAX responses stored as UTF-8 even if a non-UTF-8 charset is in use

 Priority:  low           |   Milestone:  Unassigned

 Severity:  normal        |    Keywords:  AJAX UTF-8
--------------------------+-------------------------------------------------
 AJAX responses are always sent in UTF-8. If a blog is using a non-UTF-8
 charset then the data will potentially be stored incorrectly and any text
 will often end up garbled.

 For example, if your blog uses ISO-8859-1 and some text submitted via AJAX
 contains non-ASCII characters then they'll be stored in the database as
 UTF-8 double bytes rather than their ISO-8859-1 single byte equivalents.
 Since these characters will be displayed as if they're ISO-8859-1 you'll
 just end up seeing garbage.

 The attached hack simply converts all AJAX responses from UTF-8 to the
 blog's charset using iconv.

 I've put this as low priority since most blogs probably use UTF-8. I've
 also put this in the Autosave component, but obviously all AJAX responses
 are affected.
