If this results in an empty string, results in "Untitled" (localized).
Allows:
* any alphanumeric character (unicode)
* underscore (_) as that's innocuous
* dot (.) except in leading position to avoid creating dotfiles
* dash (-) except in leading position to avoid annoyance / confusion with
command options
* brackets ([ and ]), while they correspond to shell *character class*
they're a common way to mark / tag files especially on windows
* parenthesis ("(" and ")"), a more natural though less common version of
the former
* space (" ")
