You are right. So perhaps we could add a statement:
"As RACE could either be rendered in ASCII or I18N glyphs, rendering
engine for RACE SHOULD have an option for user to select the preferred
For those who are used to rendering engines, this is actually a feature
for most common third-party rendering engine, to display the text as
glyphs or just raw 8bits.

My take that if the API is in UTF-8 as compared to UCS-4, then
Application takes native, convert to Unicode, convert it to UTF-8 to
pass onto Resolver. Resolver then take UTF-8, convert it to Unicode, do
all its funky nameprep, and convert it to RACE.
The additional processing overhead of converting to and from UTF-8 could
be removed if we were to use UCS-4 directly. And that seem to be the
common API interface.
But I may divert too much into the implementation here...

Erm. That's true...but would be nice to complete the whole picture so
there is a clear statement that caching server is involved in the
process but it doesnt really matter...
