This patch contains support for:
CS_SET and CS_GET for:
CS_LC_ALL (only when buffer = 0, CS_SET only)
CS_SYB_CHARSET, CS_SYB_LANG, CS_SYB_LANG_CHARSET
for CS_SYB_SORTORDER I do not know how to set this in the relevant tds structure, so it's commented out for now.
support for CS_SET and CS_GET for CS_LOC_PROP
with this patch you can successfully set the connection encoding and language, however only separately with cs_locale; not with CS_LC_ALL, as I'm not sure how to handle that.
I've tested all supported cases, also with valgrind for memory leaks.
It's working for me at least. I am not setting TDSCONNECTION.client_charset however, only server_charset; I'm not sure if this could lead to errors or not?
