Subject: [ruby-core:28361] [Bug #2822] Russian characters are missing from word characters types in Regexp

Issue #2822 has been updated by Benoit Daloze.


$ ri Regexp
/\w/ - A word character ([a-zA-Z0-9_])

/[[:word:]]/ - A character in one of the following Unicode 
         general categories Letter, Mark, Number, 
         Connector_Punctuation<i/i>

/\p{Word}/ - A member of one of the following Unicode general 
         category Letter, Mark, Number, Connector_Punctuation


> "a��r".match /\w+/
=> #<MatchData "a">
> "a��r".match /[[:word:]]+/
=> #<MatchData "a��r">
> "a��r".match /\p{Word}+/
=> #<MatchData "a��r">

The documentation of Regexp is awesome in Ruby 1.9, have a look ;)
