When submitting text with non-latin chars both in forum and requests as result the HEX-unicode codes of those chars is shown.
Yes, HelpSpot does not handle non-latin characters well. This is unfortunately a deficiency in PHP itself so there’s not much we’re able to do about it at this time.
The good news is that the main focus of PHP6 is on making it unicode compliant. Once PHP6 is available we’ll be making the appropriate changes in HelpSpot to fully support UTF-8 so it can properly handle most languages.
