Function looks_alike 

pub fn looks_alike(a: &str, b: &str) -> bool

Whether a and b would read as the same name: equal once reduced to a confusable skeleton and case-folded.

The skeleton is a compact form of UTS #39’s: compatibility forms and accents are dropped, the Cyrillic and Greek letters that are drawn like Latin ones become those, and l/I/1/|, 0/O and rn/m fold together. The full confusables table would add over 100 KiB to every web bundle drawing an author, for scripts no look-alike of a room member’s Latin-script name is likely to use.
