Yes, QUtf8::convertFromUnicode() and QUtf8::convertToUnicode() which
are used by QString::from/toUtf8() can be used in bootstrap tools
directly, but they can't be used through QTextStream.

At present, when QT_NO_TEXTCODEC is defined, QTextStream use
QString::fromLatin1() /QString::toLocal8Bit()
to convert from/to bytes which looks like not very well. So I think it
will be better to replace them with QUtf8::convertFromUnicode() and

Any suggestion?
