Text shows gray boxes with letters and numbers?

more options

Instead of showing certain characters/ASCII, it instead shows gray boxes with 4 letters/numbers. I have the "allow pages to choose their own fonts" checked, but it is the same with it on and off.

It was like this since I installed firefox, and fiddling with the font options did nothing. :/

Those are Unicode codepoints. They're displayed when there's no font that can display the character in question.

What are the websites where this happens?

What are the codes in question? Please provide a screenshot.
