Re: problematice metashar regexp

One of the things that may go wrong is that you substitute in the result of a substitution. Consider the first character 'h', it's replaced by '^', but '^' can in turn be replaced by '~', depending on the order of the keys, something you don't control in a hash. Maybe this effect is intentional, but if not, it could be the source of your problem. If so, replace the global substitution by a while over the characters of the string.

Hope this helps, -gjb-
