Sun Jan 20 15:08:08 2008 Martin Duerst <duerst@it.aoyama.ac.jp>
* enc/trans/utf_16_32.c: new file, currently implementing UTF-16BE conversions only. * test/ruby/test_transcode.rb: Added tests for UTF-16BE; made check_both_ways() use force_encoding differently. * transcode_data.h, transcode.c: Support for more conversion functions. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@15142 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
