Whether you choose UTF-8, UTF-16 or UTF-32 is irrelevant for functionality, but it may significantly affect compile-time and run-time performance (you may want to test your Lexer with ASCII if compilation takes too long). For example you want to work with a QByteArray containing UTF-8 data, and you want to get full Unicode support: You could either use the QByteArrayIterator and UTF-8 as internal encoding, or the QUtf8ToUtf16Iterator and UTF-16, or the QUtf8ToUcs4Iterator and UTF-32.
