* 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.
