Subject: [ruby-core:49199] Re: [ruby-trunk - Bug #7201] Setting default_external affects STDIN encoding but default_internal does not

Hello Brian,

I'm not sure what the reason was for the current state, but I can easily 
imagine a situation where stdin/stdout are the console and therefore in 
one encoding, whereas the data a script is working on is all in another 
encoding.

Regards,   Martin.
