What i do?
I create my own language file with utf8 charset. (now i set it for you to en.php with utf8 charset)

I edit mysqli_functions.php and add these lines above return line:
mysqli_query($mysql_access, "SET NAMES 'utf8'");
mysqli_query($mysql_access, "SET CHARACTER SET utf8");

I edit mysql_functions.php and add these line above return line:
mysql_query("SET NAMES 'utf8'");
mysql_query("SET CHARACTER SET utf8");

Data are stored in mysql in utf8 (I see correct characters in PHPmyAdmin).

I use recode command under linux to change files to utf8:
find . -iname '*.php' -exec recode iso-8859-1..utf8 {} ;
find . -iname '*.tpl' -exec recode iso-8859-1..utf8 {} ;
