replace any character not specified in the allowed list with the substitute character

Description:
The impetus for the custom function was to have a way to override FileMaker's built in word separators when using LeftWords (and other word evaluation functions). This tail recursive function will build a new string, substituting any non-allowed characters with the substitute character.
A call would look something like this...
Let(
[
textToFilter = TO::someField;
filterAllow = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"
]
;
cf_AntiFilter (textToFilter ; filterAllow ; " " ; 1 ; Length (textToFilter) ; "")
)
