[SyncEvolution] Char encoding in syncevo config

Hi all, I might be too frustrated recently and might have overseen something, but is there a way to set up specific char encoding in SyncEvolution configuration? The reason is that I have few old phones in Latin1/ISO-8859-15 and a newer N9 using UTF-8 While N9 works fine, I get mangled ö/ä/ü in the contacts from the older phones. I'm just thinking how can I solve this. regards
