Usually there are some provisions and transformation rules approved by
ICANN to minimize this risk. I can speak for .рф only (AKA xn--p1ai),
there are no permitted characters other than a restricted set of
Cyrillic.  You cannot have some e.g.  Greek or even Latin character in
this Cyrillic-only domain name, i.e. you cannot replace U+043E
(cyrillic small letter "o") with an ascii "o".
