But we have a tester who is Russian speaking, and yesterday I received a report from him that when using his Russian keyboard on the iPad, the app was crashing at the point that it retrieves the text from the field. This is probably some kind of bug, as the app should not crash like this, but I'll deal with that later since I think I've found the workaround. I discovered that I could use the unicodeText property of the field instead and avoid the crash, and it would retrieve the Russian characters without a problem. However, when I want back to test using the English keyboard again, I end up with garbled text, of course. I've tried using various combinations of uniDecode and uniEncode, but nothing seems to work correctly. I either end up with garbled English characters, or garbled Russian (or any other language that uses unicode characters for that matter).

Honestly not sure why this is important; after all the Unicode character 
set contains within it the
old ASCII set; so forget worrying about that difference; after all the 
whole point about Unicode is that
it (should) encompass everything.

This user name gets saved to a sqlite database, btw. I'm not sure if anything needs to be taken into consideration for that or not.
