How does smbclient know what character sets to use?

No. Newer CIFS implementations use the Unicode charset encoded in UCS-2LE
or UTF-16LE. Otherwise the charset is an 8 bit Windows charset determined
by the host locale (e.g. I think ISO-8859-1 might be like cp1252 on
Windows98 which isn't quite identical).

Unfortunately the charset isn't negotiated. The client and server simply
have to be configured to agree on which charset to use. So ideally you
really want to configure the server and client to use Unicode.
Unfortunately many folks are using specific encodings for filenames which
makes it more difficult to move entirely to Unicode (e.g. Japanese).

I don't actually know how smbclient determines the charset but using
setlocale("") to pick up LANG would still not be perfect considering the
charsets found on Unix/Linux may not be compatible with charsets in use on
a Windows server.
If I had to guess, I'd check to see if it obeys the charset options in
