Ruby warning: character class has duplicated range: `/[\s\p{Z}]+/`

[AlexWayfer]

Caught from third-party gem (r18n-core):

/home/alex/.rbenv/versions/3.3.6/lib/ruby/gems/3.3.0/gems/kramdown-2.5.1/lib/kramdown/parser/base.rb:60: warning: character class has duplicated range: /[\s\p{Z}]+/

Also I'd suggest to turn on Ruby warnings for test: https://github.com/gettalong/kramdown/commit/6c222cc7552807b517048630e15d32fc2f6a7b00

Seconded... I'm getting bit by this.

I'd also highly recommend enabling warnings.
