If I set the client charcter set cp1252, the characters get encoded, 
but wrongly. Of course I could translate these characters to the 
right ones, but it looks unproductive ;)

Hannu, 

Thanks for the problem report, and I hope Frediano's spectacular patch
does the trick.  

Just to clarify something for the benefit of others who might follow
this thread: your "client character set" entry in freetds.conf declares
the encoding your client uses.  It tells FreeTDS what to send to the
client, and how to interpret what it gets from the client.  The only
right answer reflects what you get back from locale(1).  

There is no freetds.conf entry for server-side encoding, because the
server tells us everything we need to know (whether or not we DTRT).
How we interpret what the server tells us is recorded at the top of the
TDSDUMP log.  

For correctly written applications, the "client character set" entry
should eventually become obsolete.  Unfortunately, that's much easier
said than (portably) done.  Here's a GPL example from Bruno Haible:

        
http://www.ctan.org/tex-archive/macros/texinfo/texinfo/intl/localcharset
.c

But the basic logic isn't too bad: use nl_langinfo(CODESET) if
available, else setlocale(LC_CTYPE, NULL), leaving the freetds.conf
entry as an override.  That would take care of most people.
