I upgraded to 7.5.8 back in February, I think. No issues.
Because our site has discussions that use Greek and Cyrillic I've always changed the character set from iso-8859-1 to utf-8 immediately during each upgrade.
But this time I forgot, so Greek and Cyrillic and other characters are not displayed correctly.
1) Can I just change the character set in languages/english/generic.php fro iso-885901 to utf-8 and move forward without hurting anything?
2) Is there any way to go in and repair the fix the posts that turned characters into code (like Χρόνια Πολλ)? I have this vision of one of the gurus here having encountered this and having written an sql script to do just that.
Thanks in advance for your help! We've been using UBB since 1998.
