No, because we are using strcmp to implement the lexicographic
used when sorting strings. That function uses the integer
codes for the comparison.
Is that the behaviour users want?
I imagine that French users would expect an e-acute to appear near the
unaccented e and Germans would like their sharp-S to appear near the
normal S. And presumably the Spanish like their N-with-squiggle to be
near the naked N.
We could use strcoll instead, but then the sorting will depend on the
I guess that's the big question. Is that what should happen?
In general, I would say Yes. It would seem strange if ??pfel
appears after Zuwachs, just because it's bit pattern happens to be
numerically higher. On the other hand problems can arise if a recfile is
written in a (say) iso-8859-1 locale and interpreted in a UTF8 locale.
But that would cause other problems too regardless of sorting.
