The practical example is the group membership bug I posted to this
thread with also a bug report we have in our bugzilla.

I know, that's why I raised a discussion here instead of just committing
a patch without raising the problem.

I'll do that after Jeremy shows he has read the thread :-)
No, just kidding, if we are providing the "unix charset" parameter I
believe we should also make things work when possible.
It is obvious we can't make miracles, if you use a KOIR set of
characters on disk and you are sent a japanese chracter in the file name
we have no choice but drop it and tell to switch to utf8 to fix such
But there are cases when we never hit the disk or any syscall, and in
these cases I don't see why we should be lazy and not fix an easily
fixable problem. The ldap DN stuff is such a thing, and using a struct
to hold the string making it evident it is not just another char * will
make it possible to use utf8 strings without easily be mistaken and mix
unix charset stuff with utf8 stuff.
I understand Jeremy may still find such patches uncomfortable, and
I'll take the risk, being prudent is ok for me, being conservative just
for the sake of it just sucks.
