migrating 4.0 to 5.0

[Matthias Henze]

hi,

i've still serious trouble in migrating databases createted with 4.0 to 5.0. 
the problems is still the charset. i'm connecting to mysql with php and when 
i try to use the 5.0 db german special chars are messed up. afaik 4.0 uses 
latin charset and 5.0 utf8 by default. can some one please give me a hint how 
to migrate ? i think i'm just too stupid  :-)

TIA
