I've noticed Zsh FAQ on sourceforge has a minor problem:
https://zsh.sourceforge.io/FAQ/zshfaq03.html#l19

Other way of causing word splitting include a judicious use of `eval':
    sentence="Longtemps, je me suis couch\+NOTRANS(é) de bonne heure."

It seems this is due to a bug of (some versions of) yodl.
yodl-3.05.00 has this problem, but version 4.04.02 ((Ubuntu 22.04)
correctly outputs "couch\\'e". I don't know when this bug was
introduced and when it has been fixed.

A workaround is to replace either \ or ' by CHAR().

Do I need to push this patch?
Or is it enough to use the latest versions of yodl?
