Hello, Here''s a bug we''ve run into with chomp. If you run the following code: abc = "/toheunth????????????????????".to_clr_string abc.chomp(''\\'').chomp(''/'') puts abc (where abc is really just any string with non-english characters). and you''ll get the error: IronRuby.Libraries:0:in `EndsWith'': Array index is out of range. (IndexError) from IronRuby.Libraries:0:in `InternalChomp'' from :0:in `chomp'' from /Users/martin/Kode/rbtest/test-intl.rb:3 If you remove the to_clr_string everything works fine. Otherwise RC2 looks pretty great! It seems fater and better! Thanks, Martin
