I think that that pattern is a little too broad, since it will match any 
non-ASCII Unicode character. Things like U+202E (xkcd.com/1137), U+00A0 
(no-break space), etc are valid UTF-8 characters, but not valid XML tag 
names. Neither of these two characters are matched by the TeX catcode 
check. This doesn't make any real difference for a syntax highlighter 
though.

There's a doubled plus in the middle there. The patch works when I 
remove it.

Hmm, that's really weird. Both patches work for me on my main Win64 
computer (after I fixed the extra plus). I also pulled the 
"contextgarden/context:lmtx" Docker image (Debian sid), and both patches 
worked there too. I get this from inside the container:

Is this perhaps a weird locale or encoding issue? Maybe try compiling with:

     LC_ALL=C.UTF-8 LANG=C.UTF-8 context test.tex

or

     LC_ALL=POSIX LANG=POSIX context test.tex

I'm surprised Linux is the one not working here, since it's usually 
Windows that has text encoding issues with its weird hybrid of DOS 
codepages and UTF-16+BOM.

The only other thing that I can think of is a weird library issue with 
your distro, but LuaMetaTeX is statically linked. Not sure what else to 
check here.
