I was reading https://embracethered.com/blog/posts/2024/m365-copilot-prompt-injection-tool-invocation-and-data-exfil-using-ascii-smuggling/ and hovered over the hxxtp://wuzzi[.]net link.

I noticed that the status bar on firefox shows the same text as the on-page text. It doesn't render the unicode url in full. I tried finding a bug describing this, but couldn't find one.

Sample URL:

Note that those Unicode characters are part of the E0000-E007F code block that contains tagged characters and that are not expected to display, so it is expected that you got some representation.

Special Attention: Code points displayed in this page are for special purposes. They are not displayable characters, and in particular are not allowed to be used in HTML.
