I don't quite understand: which data will be lost? UTF-8 is a perfect representation of ANY unicode character!
Roughly said for ASCII characters UTF-8 uses just 1 byte, for all other characters it uses more than what UTF-16 representation would use (e.g. 3 or 4, instead of just 2 bytes per character) ("multibyte sequence").
I am not an Unicode expert, so some details above might be plain wrong; but you can convert from UTF-16 to UTF-8 back and forth, without data loss!
Also refer to http://doc.trolltech.com/4.5/qstring.html#details: "toUtf8() returns a UTF-8 encoded 8-bit string. UTF-8 is a superset of ASCII that supports the entire Unicode character set through multibyte sequences."
Cheers, Oliver
