It is usually not necessary to escape the period when it is part of a character class (though you should experiment with the WebDNA regex library to be sure). Typically, everything inside of the square brackets except the hyphen is treated as a single character (i.e. no special meaning); in fact, if the hyphen is one of the characters you need to make part of the class, you would typically list it first, even if you used it later in the expression to notate a range.
