  20 # XXX: All this code assumes that the Unix character set is UTF-8,
  21 # which is the most common setting.  I guess it would be better to
  22 # force it to that value while running the tests.  I'm not sure of the
  23 # best way to do that yet.
  24 #
  25 # Note that this is NOT the case in C code until the loadparm table is
  26 # intialized -- the default seems to be ASCII, which rather lets Samba
  27 # off the hook. :-) The best way seems to be to put this in the test
  28 # harnesses:
  29 #
  30 #       lp_load("/dev/null", True, False, False);
