Well, the immediate reason here is this:

http://www.gnu.org/software/bash/manual/bashref.html#Definitions

"""
name
     A word consisting solely of letters, numbers, and underscores, and 
beginning with a letter or underscore. Names are used as shell variable 
and function names. Also referred to as an identifier.
"""

(ignoring that /bin/sh is not bash but the syntax is the same for this 
purpose).

/etc/rc.conf is basically a shell script containing only variable 
assignments.

I think you actually *could* have jails with arbitrary names (including 
international / utf-8 if you're not worried about formatting much) but 
only if you are going to manage them manually, not with /etc/rc.conf.
