Heh!

Right.

Yeah., it's just... what bugs me with this approach is

- If you want to switch to a certain charset, you must do this before
  the first Cygwin process in the console starts (via batch file or
  system-wide setting of LC_ALL/LC_CTYPE/LANG.

- If you want to switch the console to another charset you can't do that
  on the fly in Cygwin.  You must either exit from the console, or start
  cmd, change the locale variable in cmd, and start another Cygwin
  process from there.

It would be still be nice to have something like this, IMHO:

- Default everything to UTF-8, including the console.

- Provide the setcons tool to allow switching to another charset
  which is now valid for all Cygwin processes in the console.

That should be possible.  I have to think about this some more...
