Create unique symbols

To create unique symblols just search the vectors for the letter that you want to change. For example I want to display a smiley face every time I send a underline (_). For that I go to the underline symbol commented as (//_) and add the "1" in such a way that it will display some sort of smiley face.



Do the same for any symbol that you want.
