I don't see anything wrong with the code, but the usage comments should explicitly mention what characters you are allowing. Also, you have a fairly restricted notion of numeric (i.e. no negatives, floating-point). "$numeric" may not be the right name.

Pet peeve: $ should not be used in regexs unless you really want to allow a trailing "\n"; probably not the case here.
