Issue #1784 has been updated by Lin Jen-Shin. File test_big5-hkscs.rb added Hi, I've tested BIG5-HKSCS against trunk today, and it works fine. # ruby 1.9.2dev (2009-09-08 trunk 24791) [i386-darwin9.8.0] Many thanks for your effort. The attachment is the test code I used. It can transcode successfully in first case, but not the other. I think the failed one could be Big5-UAO encoded. Thanks again. ---------------------------------------- http://redmine.ruby-lang.org/issues/show/1784 ---------------------------------------- http://redmine.ruby-lang.org
