Letters č, ć, š, đ, etc. UTF-8 Problem

[InternetSvet]

I have a problem on my SMF forum ... Each letter of the Serbian Latin alphabet resembles something like this: Svet Informatike i Računarstva.

č instead of č.

It happened when I went to the admin panel 'Forum maintenance', and so I am Run those tasks. I have a task to convert all the bases in the UTF-8, and I do that. When I finished with that, it's all gone to hell...

Could this somehow be solved?

Double check what page encoding is being used on the admin pages (that are failing). It looks like possibly the text is in UTF-8, but is being displayed in Latin-1 or some other single-byte encoding.

The other possibility is that you messed up the conversion to UTF-8, and what's now in your database is some odd mixture of encodings. That's going to be a problem to straighten out -- do you have backups you can go back to? Use phpMyAdmin to look at the database entries themselves -- do they look correct? (and check what page encoding is being used by phpMyAdmin -- it should be UTF-8) Does your database show the expected encoding (UTF-8) and "collating" setting for all text fields, or are they wrong?
