This is tested with libreadline 8.0 on Debian.

If I create a directory named héhé where é is e + U+0301
(combining acute accent), and then try to complete hé into it where é
is the precombined form U+00E9), libreadline does not take care that é
(e with combining acute accent) is equivalent to é (the precombined "e
with acute accent" character), and fails to complete.

Readline doesn't use strcoll right now, since it doesn't work for case-
insensitive completion or case-mapping completion, and there's no
strncmp equivalent. There's no other external API to use for this purpose.
