OK, I give up.  Back to jwz: "now you have two problems.“

Although with en_US.UTF-8 on other systems, I have not had that experience.  A quick check on stuff I have immediate access to:

macOS 10.12:
$ echo 'abcdABCD' | sed 's/[A-Z]/X/g’
abcdXXXX

Ubuntu 14.04.5
$ echo 'abcdABCD' | sed 's/[A-Z]/X/g’
abcdXXXX

FreeBSD 10-stable
$ echo 'abcdABCD' | sed 's/[A-Z]/X/g'
abcdXXXX
