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.
