Yes, absolutely.

Well, no. The goal is to have filenames compatible with most systems ; and
there is no direct way to ovveride this behaviour.

Besides, you might have troubles with some filenames. On Linux/Unix systems,
the \ (backslash) and * (wildcard) are "valid" filename characters. But they
will cause some troubles to some filemanagers, I suppose. Not mentionning the
problems of removing the "*" filename for a beginner.
