charString

Required. String expression to be encoded.

The Escape function returns a string (in Unicode format) that contains the contents of charString. All spaces, punctuation, accented characters, and other non-ASCII characters are replaced with %xx encoding, where xx is equivalent to the hexadecimal number representing the character. Unicode characters that have a value greater than 255 are stored using the %uxxxx format.

The string that the Escape function returns is suitable for transmission with many protocols, such as the HTTP protocol.

Note
Because the Escape function is not designed to create a valid uniform resource identifier (URI), it should not be used to encode URIs. The JScript encodeURI method may be used to encode URIs.
