Ar an cúigiú lá is fiche de mí Márta, scríobh Johann 'Myrkraverk' Oskarsson: 
 Hi all,
 
 When I look at the CCL program that writes out UTF-8, I'm convinced, so
 far, that the bug is somewhere in the CCL interpreter rather than in the
 elisp/ccl code.
 
 Aidan, when you say the unicode in 21.4 is buggy, what exactly do you mean?
 Are there more known bugs?  Where can I see a list of them? 
Any CCL bugs I know about are fixed in 21.5. There’s no explicit list of
them, but running hg annotate src/mule-ccl.c in the 21.5 source tree, and
searching for mule-ccl.c in src/ChangeLog, will give you some pointers.
