In the Maemo5 version of eds e_contact_new_from_vcard() internally uses
a heuristic (the same as gecko uses) to figure out the charset (if the
passed string is not utf-8). If you know the charset, then of course
it's best to g_convert() the string obtained from g_file_get_contents()
into utf-8 first, then there is no need for guessing...

version 2.1 vcards actually allow to specify the encoding inline in the
vcard, but for 3.0 this was dropped. Which was maybe not the most clever
decision ever. Then again, everybody really should just use utf-8 :-P

g_convert() ?
