How is it done? Is it hardcoded Unicode map, rules or algorithm? Does it have anything to do with mdtext2 data type?
I have tried looking into https://github.com/arclanguage/anarki/tree/master/apps source code (I do not know how relevant it is, and is it up to date with deployed version) but I have not found anything useful. As I have not done anything with arc before, I would appreciate a bit of nudging in the right direction.
