The rest of the characters missing can be achieved

[eval]("String.fromCharCode( )") with the corresponding numbers can fill the rest of the alphabet/symbols

Th is not feasible because “C” is very expensive — currently 2418 characters long.

Feasible, maybe not. Possible, yes.

I don't think people are looking at JSF for feasibility

Anyway, that is how it was done initially.

PS: characters aren’t missing. They are just not defined explicitly and using optimized encoder.
