Convert a string into character codes

String to character codes

This small Python script converts a string into character codes.

JavaScript XSS payload

Character codes are useful in XSS payloads when single and/or double quote characters can't be used to surround a string (escaped or removed from the payload). The JavaScript method String.fromCharCode() converts back the character codes into a string.

Example:

String.fromCharCode(79, 80, 69, 78, 66, 85, 71, 66, 79, 85, 78, 84, 89);
