00881: UTF-8 Link misfunction with mbstring
Description: As in following link: http://www.happysky.org/wiki/Main/WikiSandbox
Chinese link make the sentences after it into links, also english link.
Apparently when mbstring is enabled, the PCRE (preg_*) functions get a more liberal idea about what constitutes an alphanumeric character.
Now fixed for 2.2.0-beta29.
Thank you :)
