I did my PhD on (malicious) visual impersonation of domain names using many of the techniques described here. There are many references to other visual doppelganger techniques included in my paper here: https://par.nsf.gov/servlets/purl/10256904 My research focused solely on the .com domain name space, so our character set was limited.

that research paper only considers ascii characters in domain names?

The paper only considers .com domain names, which have a limited character set support, discussed in RFC 1034 https://www.ietf.org/rfc/rfc1034.txt

Essentially A-Z, 0-9, and the - character, and domain names can not start with the dash character.
