Jokes aside, I'm in favor of changing some of the characters we use for binary selectors to allow it to be used in keyword/unary messages.

I'll include % in that list. For me its more useful as a way to create percentages ( 5 % ) than to be used as a binary message for keeping an ugly name from C-like languages.
�� is middle dot and it's used in some math operations AFAIR
�� is used in math also (it's used as the multiplication sign for scalars, cross product for vectors and cartesian product for sets)
One thing that would be really cool is that we can use the full power of Unicode in methods/class names. Projects like polymath and DSLs can clearly take advantage of that. Some examples I've just invented, but can be supported:

�� from: 1 to: 5 do: [:i | i + i squared ]
1 �� 3
�� anyIn: #( 1 2 4) such: [:x | x isPrime ]��
�� includes: 1

Yes I would like to have something like that for PolyMath :-)

Is it possible to use Unicode characters for identifiers already ?

I working on the port of : https://github.com/len/Domains

to Pharo. The author modify the Cuis parser, so he can do things like that : 

"��� is used for direct sums, ��� for tensor products, �� for cartesian 
product, direct product of groups, ring products, and in general for 
categorical products."

and also define ^ as a binary method:

"The ^ (hat) operator is used for exponentiation as well as conjugation 
by group elements, and for creating free modules of tuples and matrices."

 I'm not sure this is a good idea, because ^ is used also to return values.
