I see.  This is the same problem that earlier versions of Java had.
Perhaps they will fix it in C# too.

> Are there any tests cases with unicode characters > U+FFFF?

For example:

IDNA(<U+10205><U+00ed>dn.example) = xn--dn-mja7734x.example

See also RFC 3454, especially table D.2.

I use uint32_t as the Unicode code point data type, it can store 32
bits.

Good luck,
