All homograph attacks should be automatically replaced on all non-local boards. This means fake links can still be posted in (for instance) a Russian thread.
Good to know that, at least in the non-local board we do not have the issue. However non-Cyrillic characters like
ą ç í î ị ň ṇ ö ó ọ ú
are not replaced and one needs to be careful about it. They are actually different characters but still could be used for a similar kind of attack like
the Binance phishing website, they are less dangerous than the previous ones though. For example,
