--- Comment #5 from Bruno Haible <bruno at clisp dot org> ---
In musl libc, in the C locale, the mapping table does
- map x (0 <= x <= 0x7F) to Unicode x,
- map x (0x80 <= x <= 0xFF) to Unicode 0xDF00+x.

If glibc was to adopt the same mapping table, this would not complicate things
for portable programs (which have to deal with musl libc anyway).
