For the edification of us who know less - can you please name the codepoint 
in question, and what role it plays in the script?

Same question as above.

We're pretty sure COMBINING LEFT RIGHT ARROW ABOVE (U+20E1) doesn't make 
sense to allow in IDNs, I think. If we can't dump the whole "inherited" 
script, we'll have to figure out some other distinction that we can 
leverage; the first thing that needs doing is to figure out which codepoint 
we think needs allowing.
