Then I should make that OS dependant: don't mess with the default
charset in Windows and use UTF-8 on Linux.

That's because of two things: a) mmg does not use Unicode internally and
b) the wxWidgets version I use is not compiled with Unicode support.

UTF-8 is always useful as long as its stored in a file -- it just
becomes useless once we have to copy & paste it and/or use it on the
command line in Windows.

Maybe that was only on Linux, I'm not sure.

I don't think I'll find a "one size fits all" solution here (meaning: I
will have to code differently depending on the OS). I don't mind that, I
just have to do it ;)

True, but then again I think I'll keep with the default charset instead
of UTF-8.

The primary reason was that users that do use the command line (and here
I thought of Linux users) could simply copy&paste that text into their
terminal and let mkvmerge do its job.

That's one of the big differences between Linux & Windows ;) On Linux
you often use UTF-8 for Unicode support.

unconstitutional too, since clearly it de-emphasizes the commercial
nature of normal human interaction, and probably is a major impediment
to the commercial growth of prostitution. - Linus Torvalds
