I'm new to this platform and not sure whether what I'm reporting is a bug or not. But this is the issue I'm encountering.
I had a special character(Â) which gave error while using sed.
echo $'H\xc3\x82Bnc' | sed -E 's/[A-Z]*/`&`/g'
sed: RE error: illegal byte sequence
$ locale
LANG=""
LC_COLLATE="C"
LC_CTYPE="UTF-8"
LC_MESSAGES="C"
LC_MONETARY="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_ALL=
Now if I set LC_COLLATE, then the command works.
echo $'H\xc3\x82Bnc' | LC_COLLATE="en_US.UTF-8" sed -E 's/[A-Z]*/`&`/g'
`HÂB`n``c``
Is LC_COLLATE affecting the character range. Why after LC_COLLATE was set, did the code produce no error of illegal byte sequence? I'm using Mac OS 13.1
