Standard .po files declare the encoding in which they are written.  I presume
this information is somehow available in the .mo file too.  THIS is the
encoding that should be used to choose a codec to convert such text to Unicode.
In pseudocode:

KLocale::loadMOFile()
{
	...
	const char* charset = mo_file.encodingName();
	this->i18n_codec = QTextCodec::codecForName(charset);
	if ( !codec )
		fatal("No codec for %s", charset);
	...
}

QString KLocale::translate(const char* txt)
{
	const char* translation = ... lookup txt;
	if ( !translation )
		return QString(txt); // Latin1
	return i18n_codec->toUnicode(translation);
}


Of course, Qt's builtin QTranslator stuff works with Unicode form the start
(the translation files are stored in Unicode), but above we stick to KDE's
existing techniques - they can be modified later if the need arises.
