Glad you like it!

I need to things from you:
1) What is the code point to add
2) Take a look at #initializeUnicodeCodePoints and tell me which of the 
code points stored in [16r80 .. 16r9F] can be removed. (All 32 places 
are used)

Yes. Or you can simply type 'Character directSum', select, print, and 
select and delete. It could also be made that just type/select/insertIt 
(instead of doIt) evaluates an expression and replaces the selection 
with the result of the evaluation :)
