A character string generated by the MASK() function.
A character string containing formatting and space characters. Any non-space character may be used for formatting.
Extract characters that match placeholder space charaters of template.
UNMASK() removes the template characters from the formatted string, which may have been created by MASK(). If the template is not represented exactly in the string, the function returns only the portion of the string that matches the template.
unmask("(617) 555-1212", "( )| - ") -> "6175551212" unmask("(617) 555-1212", "( ) - ") -> "", because TemplateString is not identical to the template in CharacterExpression
