Thanks. I found that it also works for [...] (which is probably
the one I'll settle on for my own use) and the extended glob
ones (#, ^, ~, the latter only with #q when using extendedglob),
but also "-"!

Which harks back to 
https://www.zsh.org/mla/workers/2019/msg00465.html

Which was also asking (among other things) about the special
treatment of "-" in

$ string=- pattern='\-'; [[ $string = $~pattern ]] && echo yes
yes

(I had no feedback on that one at the time).

Here maybe zsh could extend it to all characters as doing it for
only *?[]^~#- and not others (I've not tested all possible ones)
seems a bit arbitrary.

[...]

Sorry for causing confusion there. UTF-8 é as delimiter is fine
there.

$ zsh -c 'echo /(eé"echo x"é/)'
x
/

The issue I wanted to raise was the bogus error message when
using é as a glob qualifier. It can be reproduced without the
"e" qualifier:

$ zsh -c 'echo /(é)' |& sed -n l
zsh:1: unknown file attribute: ^\003$
