That specific case also appears to have changed, e.g. on 3.4.1:
It is an intentional bug fix. See #21503. While I understand your trouble, this warning is functioning exactly as intended. How do you suggest resolving it? ---------------------------------------- Bug #21870: Regexp: Warnings when using slightly overlapping \p{...} classes https://bugs.ruby-lang.org/issues/21870#change-116328 * Author: jneen (Jeanine Adkisson) * Status: Open * ruby -v: 4.0.1 * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN, 4.0: UNKNOWN ---------------------------------------- ```ruby $VERBOSE = true # warning: character class has duplicated range: /[\p{Word}\p{S}]/ regex = /[\p{Word}\p{S}]/ ``` As far as I can tell this is a perfectly valid ~~and non-overlapping~~ set of unicode properties, but I am still being spammed with warnings. Using `/(\p{Word}|\p{S})/` is kind of a workaround, but it is slower. Edit: They do overlap somewhat, but I think the deeper issue is there is not a convenient way to express this without falling back to raw unicode ranges. -- https://bugs.ruby-lang.org/
