I noticed in SMF Team page (http://www.simplemachines.org/about/smf/team.php) that "™" is displayed as "�" in several occasions.
Also in Simple Machines Members page (http://www.simplemachines.org/about/members.php) "戦場ヶ原、蕩れ!" is displayed as "?? ?? - ".
Codepage is UTF-8, maybe some error in string manipulation code?
Those "™"s are encoded in Latin-1. I think they're OK displayed in the normal forum (UTF-8), so presumably something went wrong in the code for these particular pages.
i notice this when using my phone to browse here never noticed it in chrome tho
It's the same with Chrome. The problem appears in usernames. I suppose the same database members table is used to extract usernames for position or group.
In ISO-ANSI setup a latin-1 database is used and special chars are stored as entities. In UTF-8 setup database, tables and text fields are in utf8_general_ci collation.
Same with Opera.
