I think I coudn't express what i want to tell.
As we know, there is an option in vbulletin which prevents shouting in the messages in which all characters are uppercase.
But, Turkish has some additional characters which vbulletin can not convert into lowercase.
For example:
İ should be
i
Ğ should be
ğ
? should be
?
? should be
?
Ş should be
ş
All the other characters are the same as in English. And they can be converted. But only non-English characters are not converted, and it makes a non-standart conversion.
I wish Vbulletin could convert non-english characters also.
Thats all
