What is with this 'numbers and letters in boxes' font? Am I missing some update? Running Windows XP sp3. I get whole pages of it if its in Japanese, but sometimes it's also here and there on English pages.
Like this example I found on SE:

Those characters are generally displayed when a character is encountered that doesn't have an actual representation in the given font, or is in a character encoding that the system doesn't understand. The numbers in the boxes are the character codes.
In the Japanese case, if your font doesn't have Japanese characters in it, you'll get those instead as placeholders.
In the English case, it's special characters that your font can't represent (or that your system is perhaps not decoding properly).
