CharacterSet's predefined sets are lazy-loaded.
Pre-load them to use them in Ractors. E.g.:
CharacterSet.ascii # pre-load
Ractor.new { CharacterSet.ascii.size }.take # => 128
Ractor.new { 'abc'.keep_character_set(:ascii) }.take # => 'abc'
EOS

set.merge((range_start.to_i(16))..(range_end.to_i(16)))
end
