Unicode Control Characters should be restricted in title text (RLM, LRM, RLO, LRO, . . .)

Description

Author: tietew-mediazilla

Description:
Unicode Control Characters such as "RIGHT-TO-LEFT OVERRIDE" (U+202E)
or *all unprintable characters* should be restricted in title text.

A title including control characters breaks RC, history, contributions, etc.
A username including control characters breaks page text after the signature!
And they are hard to be linked.

... in Japanese Wikipedia, a username with U+202E is used as vandalism.

Hallo!

Last week I found
http://uncyclopedia.org/wiki/User:%C2%AD%C2%AD%C2%AD%C2%AD
containing more "Unicode Character SOFT HYPHEN - U+00AD"'s.

http://yi.wiktionary.org/wiki/category:bugzilla/02042 contains more tests. Some
of them relating to Unicode whitespace characters (see bug 02042).

regards reinhardt [[user:gangleri]]

As of r18513, the LRM and RLM marks are stripped from titles on normalization.
This will avoid creation of broken links and broken titles from cut-n-paste
from the list pages where sometimes those marks creep in.

Running cleanup on live wikis for titles where this has crept in.
Such pages can be found with prefix search on 'Broken/'.

I think r44000 fixed this back in 2008. Closing.
