Then I guessed your question right :)  As I said, basically you can't
know the encoding, unless you're using a protocol that supports this
feature.  I don't know whether telnet (I assume that's what you're
doing) supports it.  If not, you've no choice but making the encoding
configurable by the user.

I think 0 is correct.  Have you checked whether changing the encoding
actually suceeded?  The GLib API doc describes when you're allowed to
set it.  Also, are you sure it fails in g_io_channel_read_chars(), and
not somewhere else when you're trying to use the data?

It's in the docs.  Right there on the frontpage, there's a link
"Character Set Conversion".

You're welcome ;)
