I have tried Firefox and Chrome and on Ubuntu 14.04 LTS, and there seems to be a sizeable chunk of Unicode characters that I cannot render.

Here is one example, and here is another example.

What is the best course of action to diagnose the root cause and fix the missing characters?


Install package ttf-ancient-fonts.

sudo apt-get update
sudo apt-get install ttf-ancient-fonts

In order to see the missing characters, you need to install a font which contains them.

I've found that Symbola contains the best range of characters.

  • Download the zip file.
  • Install the two .ttf fonts - if you double click on then, you should see a font preview, click the "Install" button.

With the latest version (8.0.0) I'm able to see the dog symbol 🐕 and the slice of pizza symbol 🍕.

See: enter image description here.

  • Or just sudo apt-get install fonts-symbola and then restart firefox ;) – rubo77 Aug 7 '16 at 22:27

The most comprehensive font package I have found is font-noto. Installing this has always fixed whatever font-display issues I was having:

sudo apt install fonts-noto

Then, restart your browser and everything should work as expected.


I tried to view the characters on my computer (See signs and symbols). Enter the Unicode-code in the search-window. It looks that the symbols mentioned are not rendered yet (These characters are in the Supplementary Multilingual Plane). See also http://www.ltg.ed.ac.uk/~richard/unicode-sample-3-2.html.
