More and more recently I see empty rectangles in text areas on the web. I think it is Ubuntu 14.04's character encoding/Unicode libraries not being up to date but I don't know. I also think it is mostly emoji but cannot actually see the characters to know for sure.
How can I fix this?
The webpages do have a
<meta charset="UTF-8"> in them.
