for undefined conversions.

* transcode_data_iso_8859.c: Changed from character constants
  ('\xC2') to integer contants (0xC2) for shorter files and
  better readability; eliminated duplicated tables; changed
  from -1 offset to actual UNDEF entry (not yet distinguishing
  UNDEF and ILLEGAL correctly).

* test/ruby/test_transcode.rb: added a test for UNDEF conversion.
