Character problem after upgrading from 1.3.2 to 1.4.4

[javelinworld]

I updated from 1.3.2 to 1.4.4 and I have pb with accentuated character like "é" "è" "ê"
The main langage of my gallery is french.
The  URL : http://jerome.chevillat.free.fr/cpg132/index.php

I have "Ath讥s 2004 " instead of "Athènes 2004"... the problem is the same in every langage !!! I always have "Ath讥s 2004 "

Moreover at the bottom of the main page in the last additions files I have something strange : Jarkko KOSKI VĈČļ/span>

I do not understand why /span is written

has been asked before. You have non-unicode text in your database, but you now use utf-8 (unicode). Either use the charset you used when originally populating the content or use charsetmgr.php to convert your database's textual content to utf-8 (recommended). Please search, this has been asked before. The html tag </span> probably shines through because one of your special chars that shows up garbled equals a >, no need to worry about this particular issue. Fix the garbled special chars first.

Ok thanks
But charsetmgr.php said that I already use  utf-8...
I tried iconv with the same result...

I have to modify each corrupted word now
