That's the same as ISO-8859-7 and different from CP1253.

You mean FreeTDS can't locate the server? Try TDSDUMPCONFIG, if that's the
In another log you posted, I note the client charset is ISO-8859-1, the
default (Latin1 and not, as you know, Greek). That would be consistent with
your report: iconv would read your Greek text, encoded in ISO-8859-7, and
attempt to interpret it according to ISO-8859-1, yielding some Roman
characters and some invalid values. Blech! Trick is to persuade FreeTDS
that the client is using ISO-8859-7.
1. What is the server character set?
2. Are the columns holding Greek text in the tables defined as varchar or
Right now, FreeTDS still does not use iconv to convert single-byte character
data -- however encoded -- meaning that [var]char and text columns must use
the same encoding as does the client. This will change in the (probably
near, certainly approaching) future. We recently started handling,
experimentally, UTF-8 client data, but we're far from done with that.
