This is a helpful extension for Scratch projects that adds more features to text and character editing and manipulating. It adds the two JavaScript functions fromCharCode and charCodeAt. It also adds functions to convert HEX <=> DEC Numbers. Controls: press h for hex => dec, press d for dec => hex, press c and h at the same time for charCodeAt, press c for fromCharCode.
Don't be surprised! The variable UNICODE may look corrupted in the online version (it's not), but when viewing it in the Offline-Editor you may see that it got the COMPLETE UNICODE TABLE in it (!!) so it may lag offline. (See http://unicode-table.com/) Contains all values from 0x0000 (0) to 0xffff (65535)
