Hi Santiago,
Thanks for testing that.
What do you get when you run the stand-alone example I gave in the
commit log and in the test?
printf 'j\x82\nj\n'|LC_ALL=en_US.UTF-8 grep -P j|cat -A; echo $?
For me (using pcre-8.33), it works the way I want and both matches:
jM-^B$
j$
0
Hmm... I see that with debian unstable's 8.31-2, it does indeed act differently.
I may have to think about excluding pcre support when the version
doesn't work the way I want.
