Ok, thanks!
I have used iconv to convert text from UTF-8 to ISO-8859-1.

First for forum table of db.

iconv -f UTF-8 -t ISO-8859-1  forum_table.sql > ok_forum_table.sql 

And now character and text in forum table is ok (and are show ok in board index). smile

But when i try to convert the posts table also, i have this error.

iconv -f UTF-8 -t ISO-8859-1  posts_table.sql > ok_posts_table.sql 
iconv: illegal input sequence at position 1719812

Hi yonash, thanks for the reply.
My browser is allready set to UTF-8.

Hi,
sorry but i don't find any solution in older post.

I have upgrade my punbb 1.2 to 1.3. It's all right but now i see strange characters in my board (like 'à iù! ì).
This character is also in posts table of db (with "utf8_general_ci collation").

With punbb1.2 and db =  utf8_general_ci collation (with à characters also in posts tables) it's ok, character are automatically converted.
With punbb1.3 and db =  utf8_general_ci collation (with à characters also in posts table) it's not ok and the wrong characters are show.

I'm a lot confused about UTF-8, encoding, etc.., can someone help me?

I work on local system for now, so i can do all to solve it.

Sorry for my bad english.
