``` <meta charset=utf-8> آَ ``` Release 142 (Safari 15.4, WebKit 17614.1.5.16) This combo is a typo, but even so, a browser crash is unwarranted. Similar combos may also cause crashes.

Thanks for reporting this issue. Unfortunately I am not able to reproduce the crash by just copy-pasting the "آَ" content and neither by constructing a test case by using the associated HTML entities (&#1614;&#x64E; etc). Would you mind attaching the actual markup that reproduces this crash, please? Thanks!

It seems that you didn't copy the <meta> tag as well. Copy and paste this in the address bar: data:text/html,<meta charset=utf-8>آَ

What OS version are you reproducing this on? Can you find a crash log (via Console.app) and attach it?

Created attachment 457104 [details] screenshot Occurs on macOS 12.2 and also on iOS 15. It doesn't crash the browser, just the renderer. Here's a codepen: https://codepen.io/mustafa0x/pen/QWarrZe

This is the same stack trace as rdar://87542346, which got fixed in macOS 12.3. I can reproduce on macOS 12.2.1 byt simply opening this bugzilla page. The fix was not in WebKit, but in underlying system frameworks.
