Subject: [ruby-core:24044] Re: [Bug #1681] Integer#chr Should Infer 	Encoding of Given Codepoint

We have String#encode (without any arguments), which transcodes to 
default_internal (and in addition, doesn't raise an exception for 
invalid byte sequences,..., which may be a security issue), so I don't 
think using Integer#chr with a default encoding of default_internal 
would be such a big problem.

Regards,    Martin.
