Oh well... there is the explanation for the double conversion. I should
have checked the docs for QTextStream, in particular the "<<" operator
with a QCString argument:
The string s is assumed to be Latin1 encoded independent of the
Encoding set for the QTextStream.
Who the f*ck told that operator to mess with the encoding?
Of course toCString() can't work correctly, then.

Sounds good.

For toCString() to work correctly, the "<<" operator should write the
bytes unmodified (i.e. use QTextStream::Latin1 encoding). This should
also be the fastest mode (not that it would matter much).
Since we also use "<<" with a "const char*" argument, which has the same
properties, the cleanest solution is to do it this way:
stream.setEncoding(QTextStream::Latin1);
stream << "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
stream << doc.toCString();
If we ever replace the QTextStream with a std::ostream or another "byte
transparent" kind of stream, this variant will continue to work, while
the other one won't.
On my system, this creates a correctly encoded project file in both
Latin-15 and UTF-8 based locales. I'll check the Windows part this evening.

Didn't I mention that already? ;-)
And the combination of encodings and Qt is a royal PITA.
