[Mediawiki-l] how to set default mediawiki charset ?

[Riccardo Veraldi]

Hello,
I'd need to set charset for my mediawiki 1.15.3 to latin1 instead of 
utf8 default

this because I cannot convert my mysql DB to utf8.
All tables in mysql DB are set to latin1.
if I convert it to utf8 I have key lenghtness errors.

Actually special characters are mangled in my mediawiki pages since I 
upgraded from an old mediawiki version 1.5.*
to version 1.15.3

how can I Solve this ?
is there a way to set latin1 charset in mediawiki 1.15.3 ?

thanks

Rick
