The problem is that a word opcode doesn't match if you define a
character with lowercase. It matches if you define the character with
uplow. I created two minimal tables
(tests/tables/lowercase_with_unicode.ctb and
tests/tables/uplow_with_unicode.ctb which define a few characters and a
few contractions (using the word opcode). If you load these in
lou_allround and try to translate the word "gross" you correctly get
"g^". However if you translate "gro\x00df" the contraction only works if
you define \x00df with uplow (and fails with lowercase). There is a test
case to reproduce this (test/uplow_with_unicode.c)
Incidentally I believe that this is the same bug as the letter def bug
that Mesar has been raising.
Thanks
Christian
