I agree, I don’t think it would be good to require this.

I added a simple algorithm that converts a sequence of 16 bit code units
to a sequence of Unicode characters, inserting U+FFFD characters when
bad surrogates are used:


Nothing in Web IDL references this algorithm.  Other specs can do so if
it is useful.
