Re: [idn] homographs in TrueType fonts

["Mark Davis" <[e-mail]>]

Eric, I updated the file on
http://unicode.org/reports/tr36/draft/confusables.txt incorporating your
list (and others).

There is also the file
http://unicode.org/reports/tr36/draft/confusables-raw.txt, which contains
raw data; it is not reconciled, and not closed. The items with a number or
'skip' in the third field are usually from your data. I do remove some of
the data where you have identicals because they are basically font bugs.

Anyway, comments welcome.

‎Mark
