[AdamWr]

Steps to reproduce

1. Add this rule:
   ||t66y.com^$replace=/[\s\S]*/Test/
2. Go here NSFW - https://t66y.com/

Expected behavior

Content should be replaced by $replace rule

Actual behavior

$replace rule doesn't work

Your environment

• AdGuard for Windows 7.2.2917 (CL 1.4.157)

It seems that it happens on other websites too - AdguardTeam/AdguardForWindows#2950

Both websites are non-UTF8 websites.

Guys, as I've said before - use Latin1 for $replace rules when you don't know what encoding to use.

But, in previous ADG 7.1.2817 all user rules work fine. On non-UTF8 websites too, without any special encoding for rules...

@moraks Yes, it is regression.
