Oh, ok.  So I understood right.  But that's exactly what I didn't want
to do.  The idea is that, even though UTF-8 is used for the filename
conversion, the console should default to standard ASCII behaviour,
unless you specify another charset before starting the first Cygwin
process in the console.

I'm also wondering if we should perhaps only allow either ASCII or
UTF-8 as console charsets, but for now I don't want to touch this
more than necessary.  I just found that the console I/O doesn't work
well for non-ASCII chars anyway.  The core function which echos input
to the terminal only handles singlebyte chars, which can be easily
reproduced using copy/paste.  Oh well.
