incorrect display Facebook graph non-English character on andriod device

I have problem when display facebook user’s data string that contains non-english character (Thai) on andriod device

for example:
“???” i got something like “B?#A#!@!-#L” in device

But testing in simulator with BobDickinson’s facebook-helper module its display correctly.

I also tried Corona facebook example project on device but problem still exists

Anyone had a chance to look at this problem?

Thanks in advance. [import]uid: 133712 topic_id: 24930 reply_id: 324930[/import]
