I think that it is somehow related to the new USTS10 collation
implementation in C Gavin just merged in.  But it is not so obvious what
is going on.  Looking at the CI, Ubuntu 22.04.5, Ł (from @L{}) is sorted
before ł (@l{}), while it is not the case in the reference result.
This, however, does not happen on a recent Debian.  Also, it does not
happen for the similar encoding_index_utf8_enable_encoding tests that
are the same, except that the input file in UTF-8 encoded.  The Perl
version in the CI is 5.34.0, which is older, but not so old.  A
possibility could be that there is something different with iconv, maybe
a difference in UTF-8 normalization?

Gavin, any idea?
