By default, Qt assumes that your source files are encoded in Latin-1
(see QTextCodec::codecForCStrings and
QTextCodec::setCodecForCStrings). This affects the conversion of
C-Strings to QString, as well as the output of QString::toAscii().

You probably need to tell Qt the correct encoding of your source
files. If you don't know, a good guess is the system codec :

    QTextCodec::setCodecForCString( QTextCodec::codecForLocale() );

If you need to output a QString to the console, I would also use
str.toLocal8Bit() instead of str.toAscii(). Although if you set the
codec for C Strings to the system codec, both will probably return the
same thing.
