  22 # XXX: All this code assumes that the Unix character set is UTF-8,
  23 # which is the most common setting.  I guess it would be better to
  24 # force it to that value while running the tests.  I'm not sure of the
  25 # best way to do that yet.
  26 #
  27 # Note that this is NOT the case in C code until the loadparm table is
  28 # intialized -- the default seems to be ASCII, which rather lets Samba
  29 # off the hook. :-) The best way seems to be to put this in the test
  30 # harnesses:
  31 #
  32 #       lp_load("/dev/null", True, False, False);
