"homoglyph bundling" is referred for grouping all variant strings that
have either Exact/Typo similarity for a certain string.
This problem arises with language which ha homoglyph(Exact/Typo
similarity) characters with other language.

As SaudiNIC we are working on system(in final stage) to solve this issue
for Arabic Scripts this system can also work with other scripts.

I received the following interesting query from the "European Registry  
of Internet Domain Names".

I had not heard the term "homoglyph bundling" before. Where does it  
come from?
