printf 'foo\x80bar\n' | busybox grep f.*b
<nothing>
printf 'foo\x80bar\n' | LANG=C LC_ALL=C busybox grep f.*b
foo´┐Żbar
printf 'foo\x80bar\n' | LANG=C LC_ALL=C busybox grep f.b
<nothing again, why?>

Breakpoint 1, regexec (preg=0x7ffff7ffe668, 
    string=0x7ffff7ffec00 "foo\200bar", nmatch=1, pmatch=0x7ffff7ffe6a8, 
    eflags=0) at src/regex/regexec.c:983
then returns 1.
