I am testing mobile extensions' contacts feature(Also QFile and QString feature). I wanted to read the contacts' fields and output to a file(using QFile and QTextStream).

Because there are CJK characters in the contacts, so I got quite a lot of '?' when I viewed the output file using Y-Browser.

Maybe solving following problem would be helpful to a final solution:
1) What is symbian's native encoding(UTF-8?)
2) Is QString Unicode encoding? When read into QString, do I need to transform the native bytes from contacts list to Unicode? When write to file, do I need to transform Unicode to native encoding?

Thanks in advance,
