From: Nobuyoshi Nakada Date: 2011-02-10T07:28:21+09:00 Subject: [ruby-core:35175] [Ruby 1.9-Bug#4386] encoding: directive does not affect regex expressions Issue #4386 has been updated by Nobuyoshi Nakada. US-ASCII only regexps are set to US-ASCII encoding, same as US-ASCII only strings. It's intentional. ---------------------------------------- http://redmine.ruby-lang.org/issues/show/4386 ---------------------------------------- http://redmine.ruby-lang.org
