  | If you are talking about localized names,

Yes, that's what matters.    And yes, it is hard to know what to do.
I think I'd just prohibit a small set of likely dangerous characters
(like \n, and probably \r, maybe ESC,) and leave everything else
(everything that's possible, a few other characters are made impossible
by the format).
