I'm 70% confident that using localized strings in keys like this won't cause problems. @Manishearth agrees that it is fine. CC @robertbastian @pedberg-icu

Not sure why it's stuck

It definitely does in the cldr-icu tooling: if in tools/cldr/cldr-to-icu/src/main/resources/ldml2icu_locale.txt I tried to use

//ldml/characters/nestedBracketReplacement[@bracket="(%A)"]  ; /nestedBracketReplacement/$1

(or quoting the $1) I got from LdmlConverter

Exception in thread "main" java.lang.IllegalArgumentException: invalid character in unquoted resource bundle path segment: （

If it were quoted would it work ?

ICU's key space is invariant safe ascii or ebcdic I think.

JSON should be ok with anything that's not certain spacing or illegal chars.

@robert @sffc @srl295 Yes, ICU resource bundle keys must be invariant chars (subset of ASCII): See https://unicode-org.github.io/icu/userguide/locale/resources.html#accessing-by-key
