Attempting to transcode a traditional Chinese character from UTF-8 to EUC-TW results in a "code converter not found" error. This character exists in Unicode (U+8B6F), and if it were missing in EUC-TW, then I would expect "Encoding::UndefinedConversionError" rather than "Encoding::ConverterNotFoundError". Relevant code and Ruby versions are shown below for reproducing this issue. $ ruby -v -e '"шн?".encode("EUC-TW")' ruby 1.9.3p0 (2011-10-30 revision 33570) [i686-linux] /tmp/test.rb:3:in `encode': code converter not found (UTF-8 to EUC-TW) (Encoding::ConverterNotFoundError) from /tmp/test.rb:3:in `<main>' $ ~/ruby_vm/nightly/bin/ruby -v -e '"шн?".encode("EUC-TW")' ruby 2.0.0dev (2012-09-07 trunk 36920) [i686-linux] /tmp/test.rb:3:in `encode': code converter not found (UTF-8 to EUC-TW) (Encoding::ConverterNotFoundError) from /tmp/test.rb:3:in `<main>' -- http://bugs.ruby-lang.org/
