I'd like to learn some details about encoding settings on your side.
1. Did you use mysqldump to create the script that you sent me earlier?
2. From the script, I can see the database stores data in UTF-8, is it correct?
3. Since the character in the dump sql is already broken, could you try, if you temporarily change the connection charset to utf-8, does the same dump contains the correct character for accented letters? Or please try --default-character-set=latin1 as one of your dump option.
4. Since all charset settings on your side appear to be latin1, are all databases hosted on the mysql server using UTF8 as the encoding? Including the one serves TapirLink?
I am trying to reproduce your environment here.
