Good point. I had a brief look at
http://www.w3.org/International/multilingualweb/lt/drafts/its20/its20.html#allowedchars
with the regex from Pablo (thanks a lot for that!), the following 
examples don't work:

- windows file name "[&#x20;-&#x1ffff;-[&lt;>:&quot;\\/|\?*]]"
- no character (that is, empty string as content of allowedCharacters 
attribute. Is this ok?
- all word characters "\w"
- allows all characters between U+0061 and U+00FF except the characters 
SPACE (U+0020), TABULATION (U+0009), CARRIAGE RETURN (U+000D) and LINE 
FEED "(U+000F). [a-&#x00ff;-[\s]]"

Agree.

Best,
