Can you give an example?
firstname.lastname@example.org -> email@example.com should not require
converting internaut.com (straight ASCII), right?
If internaut.com contained an international character set (e.g. UTF-8),
then a conversion should still not be necessary in RADIUS, since DNS
lookups aren't done on the realm portion, right?

I agree that conversions may need to be done in some circumstances. But
since this is not a common case (might even be nonexistent in RADIUS),
there is no need to optimize for it.

The implied requirement is that users send domain names in the same format
that they are included in the RADIUS proxy routing table. As Alan noted,
this assumption seems to work today.

I'm even less educated than you. Perhaps we need to bring in an expert to
