Converting 👁👄👁.fm using UTS46 should yield xn--mp8hai.fm but gives:

I don't get it. In the mapping file I see:

uts46_map(128065) -> 'V';

so that codepoint is valid.

[benoitc]

yes for uts46 it is valid but not idna2008

I closed it, I think you are right and that it's not supported. Since this library is about idna it doesn't make sense to support it?
