I had a discussion a few months back with someone regarding the problem of using non-ascii characters in both a Windows program and Web program. The Windows program is Charset based (and the characters are stored in the data file in this way) but the Web is utf-8 based and characters entered here don't appear correctly in the TPS file.
I seem to remember it was around either Latvian or Hungarian character sets.
I remember the answer at the time was less than completely satisfactory. I've recently added some support which makes the above layout possible, however there is some coding I need to add on a language-by-language basis. (I've only done Polish so far). So if you are using foreign characters, and mixing them between windows and the web, please let me know.
Cheers
