Some of these are more compelling than others, the one screenshotted is probably the best.

Comment 11 by xis...@gmail.com, Aug 25 2017

I think the summary should be changed to “URL spoofing using combining marks”. Then thai/lao/malayalam/mongoian/tibetan are not the only problematic script system, they seem like the tip of the iceberg.

Update a IDN spoofing in Malayalam using (U+0D1F),(U+0D20) .

This has to be dealt with in a separate bug. There's no script mixing. U+0D1F and U+0D20 look like Latin 's' and 'o', respectively.   Unicode util web site is down at the moment and I haven't checked if U+0D1F and U+0D20 are considered confusable with 's' and 'o' (I guess they're). If they're and 'so.com' is in the top domain list, it'd be blocked. 

 bug 726950  took care of mixing Latin + a non-Latin script.
