Thanks for reminding me what 'stable' means in this context. What I am
driving at is that... stable or not... I just need sort to do the job
right, which in this particular use case appears not to be the case.

In other words when I use the vim :sort command the output should have
index entries starting with É under letter E... Œ under letter O, etc.
which as far as I know is the way things work with French language
indexes.

As quoted above the ':help :sort' documentation proceeds to inform me
that I will have to 'try it out'. Seriously?

As it happens my original post explained just that. I 'tried it out' and
the result is either of two things: I did not 'try it out' right (user
error) or vim does not sort correctly (bug).

Now you're telling me that it's not vim's fault (couldn't care less
whose fault it is)... it's "the libary's".

So what's the next step?

Should I determine what library is at fault so I can discuss it with the
developer... or should I ask vim to kindly switch to a library that
actually works such as GNU's (coreutils) which as tested (cf. original
post) does sort correctly?

Thank you,

CJ
