; This alias is usefull to quickly convert characters to ascii values.
;
; Usage: /ascii [[-rh] <input>]
;
; /ascii for a list of all characters.
; /ascii <text> to convert the text to the ascii values of all characters.
; /ascii -r <ascii values> to convert the ascii values to normal text.
; /ascii -h <text> to convert the text to the hexadecimal values of the characters.
; /ascii -rh <hexadecimal values> to convert the values to normal text.
