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?
