Forum Error character accents

[محروم.كوم]

Hello, after I upgraded my forum to 4.0.2 PL4, I got errors accents. The phrases appear in this way:

Code:

T?³picos do F?³rum

Publicit??rios
I realized that no good I remove my default language and send it back he did not complete .. sometimes it does not appear in Acimcp - Languages, and when I enter again, it inserts, but no arranges the letters ...


I've done:

Tools.php
rebuild tables
master removes language
table removes language, phrases, phrasetype

What else can I do to get back to normal my sentences? __DEFINE_LIKE_SHARE__
