utf-8 is only a 16-bit (a.k.a. wide) character set. All this is
available in C. For example, the utf-8 compatible printf is called
wprintf.  All these are controlled by the LC_CTYPE environment variable.
You could set this in your code (via setenv in C) to some obscure
locale, like the suggested Burmese, and then use a character from that
in your work. It is actually very little different in your code (depends
on your code) to do this. Granted this has 'hack' written all over it...
