Encding.find()は、stringまたはsymbolを受け付けるとrdocにありますが、
symbolを渡したときはTypeErrorになります。これは意図された動作でしょうか?

~~~
% /usr/local/stow/ruby-2.2-dev/bin/ruby -e 'Encoding.find(:Shift_JIS)'
-e:1:in `find': no implicit conversion of Symbol into String (TypeError)
  from -e:1:in `<main>'
~~~

ruby-2.1.2とruby-2.0.0p481でも同様にTypeErrorとなります。
