Subject: [PATCH] Print control characters, even though they are normally not
 visible.

With cons25, there are printable characters below 0x1B. This is not the
case with ASCII, UTF-8, etc. but in this case we just have to.

Also don't set LC_CTYPE to UTF-8 when libteken is compiled without UTF-8
in the demo-application.
