 OK, I'll try to CC it.

 Well spotted, Sir!  I'd forgotten that in my clfs builds I do
indeed recode the messages and pages.  So much for my memory, and my
apologies for spreading confusion or lies.  The "guilty" part of the
script is now attached,  I guess my point now becomes "if even I can
do it, any fool can get an all-UTF-8 system".  Sorry.

 That probably also explains why some quick testing in a tty on this
system (LFS-6.3) failed totally to provide anything other than
English messages  of 'No manual entry for foo'.

 I'll maybe get around to trying other terms in a few days.  No
promises, I'm afraid.  Not quite sure if I've yet picked up
everything you want to establish - the earlier tests were just run
with 'LC_ALL=xx.YY-UTF-8 man foo' ?

 You suggested that, or something very like it, to me before.  On
that occasion I didn't manage to make it work.

No, not on my modified clfs yesterday, nor on the LFS-6.3 I'm using
today.
