good one: s/of coarse/of course/;
unless...
then there is: s/for stringent/more stringent/;
anyway, if you demand that the user enters a specific string in a form,
why bother?
so let's assume you will be testing the values for legitimate characters.
and/or maybe a set of values.
other than that, the problem would be you would want to let the user know
which input is bad, and make them re-enter the data.
we are entering total cgi territory, here. better stay with that list.
