# XXX: All this code assumes that the Unix character set is UTF-8,
# which is the most common setting.  I guess it would be better to
# force it to that value while running the tests.  I'm not sure of the
# best way to do that yet.
# 
# Note that this is NOT the case in C code until the loadparm table is
# intialized -- the default seems to be ASCII, which rather lets Samba
# off the hook. :-) The best way seems to be to put this in the test
# harnesses:
#
#       lp_load("/dev/null", True, False, False);
