Ask HN: How does HN sanitizes input?

5 points

6 years ago

I have noticed that it is not possible to enter HTML or ASCII emoticons, but on the other hand, it will allow a wide range of letters from different languages.

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.
