Encodes String objects so they can be read on all computers.
The required charString argument is any String object or literal to be encoded.
The escape method returns a string value (in Unicode format) that contains the contents of charstring. All spaces, punctuation, accented characters, and any other non-ASCII characters are replaced with %xx encoding, where xx is equivalent to the hexadecimal number representing the character. For example, a space is returned as "%20."
Characters with a value greater than 255 are stored using the %uxxxx format.
Note The escape method should not be used to encode Uniform Resource Identifiers (URI). Use encodeURI and encodeURIComponent methods instead.
