As much as you like it, there is a slight problem with it. Linux will
currently throw virtual consoles out of UTF8 mode when reset is called.

Also see:

These posts argue about terminfo being the culprit. But how can terminfo 
be at fault, when `echo -en "\ec"` triggers it too?

Since I am in a patch mood, here's my stance/patch, which is compile and 
run tested and behaves as expected (both with `echo` and `reset`).
