Description (partial)

Symptom:
With Cyrillic characters, you can craft words, that look identical, but since they are technically a different character they can’t be matched using existing tools/content filter possibilities.

for example, the below words look exactly the same, but, one will be detected only, The first one does not match as the M is from the Cyrillic character set.
