Hello,
% REGEX='^[þ-ā]+$'; [[ ÿ =~ $REGEX ]] && echo yes
zsh: failed to compile regex: invalid character range
þ is decimal 254, ā is decimal 257. If one splits this range on 255/256 decimal:
% REGEX='^[þ-ÿĀ-ā]+$'; [[ ÿ =~ $REGEX ]] && echo yes
yes
Then it works. Bash 3.2 doesn't print error message, but first regex doesn't yield "yes" in output (in Bash 4.4 both work). Also, Mikachu checked that `setopt rematchpcre` makes first regex work. I checked that the range works if treated as Zsh pattern.
All in all, it seems to be located in the regex library, as Bash shares same issue, and pcre works fine. Has anyone a hint where to report this?

Looks like regexp is part of glibc, so:
