Well, we can be aggressive, but this seems to be a bit too stretchy. We do have a lot of not-so-likely entries in our supplementary table to be on the safe side. So, I'm not saying this should not be in. 

jshin: Uh oh! This issue still open and hasn't been updated in the last 14 days. This is a serious vulnerability, and we want to ensure that there's progress. Could you please leave an update with the current status and any potential blockers?

If you're not the right owner for this issue, could you please remove yourself as soon as possible or help us find the right one?

If the issue is fixed or you can't reproduce it, please close the bug. If you've started working on a fix, please set the status to Started.

Thanks for your time! To disable nags, add the Disable-Nags label.

Definitely not for M66. Maybe, M-67. 

Need to look for similar cases in the set at https://goo.gl/2j6r18 . 

U+00E6 æ => a e
U+04D5 ӕ => a e

Borderline list: 

U+044E ю => i o  ? 
U+044B ы =>  b i or b l 


The above characters + diacritics will be handled automatically because diacritic removal is done earlier.
