The 'echo -n' could also simply be replaced by 'printf'.

Concerning portability the question in the first place is IMO what to
do with those '\u....' . - I don't think this is standard, or is it?

So if it's non-standard we could use arbitrary common but non-standard
shell features.

Like the shell built-in 'printf' without $'...' to use just '...'.
Or IMO best just the already suggested ANSI strings  var=$'...' .
