> \hjcode 769=0 % combining acute counts for 0 I just realised that you expected 0 to mean “0 characters in length”, by analogy with the examples Hans gave with 1 and 2, but for \lccode 0 has the effect to deactivate hyphenation. (Obviously I don’t know which it is for \hjcode, otherwise I would just say it).)
Best,
