Unicode and using alternate characters

[Christ, Bryan]

This posting is a response to the person asking about how to "detect"
whether or not they can print alt characters (unicode on/off).  Sorry, I
don't have the original posting.

As Thomas stated, setlocale() does require a bit of trust.  I'm using
getenv("TERM") to check for "xterm".  If it's not xterm, I won't show
alt char.  Obviously, I'm missing out on some instances where the alt
char *could* be displayed but I prefer the "better safe than sorry"
approach.  Even with this approach assumes that TERM is set correctly.
