Investigate ODBC driver text encoding

[SwooshyCueb]

For EL10, it appears that we use the wide-character version of the PostgreSQL ODBC driver, but we do all our ODBC operations in ANSI mode.

irods_testing_environment/irods_testing_environment/odbc_setup.py

Lines 26 to 31 in b3f6a84

	[PostgreSQL ANSI]
	Description = ODBC for PostgreSQL
	Driver = /usr/lib/psqlodbcw.so
	Setup = /usr/lib/libodbcpsqlS.so
	Driver64 = /usr/lib64/psqlodbcw.so
	Setup64 = /usr/lib64/libodbcpsqlS.so

Somehow, this works. Let's investigate why, and whether we should be doing something else instead.

I would imagine that ANSI is a subset of wide character mode...
