Usage:
       PreventWSNonASCII form-save client "/p4/common/bin/triggers/PreventWsNonAscii.py %formfile%"

This script is designed to run as a form save trigger on the server.  It will cause
a workspace save to fail if any non-ascii characters are present in the workspace spec.

It also will block odd characters from the workspace name.
