You're right that there isn't a good standard way to configure this, but a lot of terminals should be able to do it. The magic phrase is “word characters”. I know Konsole, gnome-terminal, iTerm2, Terminal-dot-app at least have this setting.

Yep, I know about that (and WORDCHARS in zsh, for keyboard navigation). The thing is, though, UUIDs overload the dash character. I don't want dashes to be word characters except for a UUID.

(ULID representations also are shorter because they use a wider character set, which is nice though not critical.)
