Public bug reported:
Binary package hint: grep
A command like "grep '[abcd]'", but with 8-bit charaters in place of
[abcd], does not work properly. It fails to match anything.
Why I care: constructions like this are used when building rus-ispell
packages (Russian dictionaries for spell checkers) in order to generate
variants of use of the Cyriilic Yo letter. Because of this bug, the
resulting dictionaries are incomplete.
Test script:
===
#!/bin/sh
LANG=C
LC_ALL=C
export LANG LC_ALL
printf '\100' | grep -c `printf '\100'` -
printf '\100' | grep -c `printf '[\100]'` -
printf '\200' | grep -c `printf '\200'` -
printf '\200' | grep -c `printf '[\200]'` -
===
Output:

Expected output:
