There is a POSIX standard for portable filenames but no requirement
to restrict users to it. By default the only characters not allowed in a
filename are / and NUL - which has the advantage of supporting filenames in
just about any encoding without problems (useful if you are serving files
for international workflows).
BTW you have left out the fun and games available by use of
backspace and vertical tab in filenames - I have seen sysadmins lose half a
day trying to delete files like that (* is another favourite component in
sysadmin trap filenames).
