Web Browsers Unicode Support; Firefox 4 Sucks

Xah Lee, 2011-04-06

The unicode support in Firefox 4 sucks.

Here's a test page to see how your browser support unicode: Web Browser Unicode Support Test Page.

Here's a screenshot of Firefox 4.0.

Screenshot of Firefox 4.0 on Windows, showing a lot missing characters.

All other browsers show all characters, while IE9 misses just a few.

With respect to unicode support, the best to worst are: Google Chrome, Safari, Opera, Internet Explorer 9, Firefox 4. (all latest public release on Windows as of 2011-04-05.)

To fix the Firefox problem, you have to use CSS to specify font. (See: Best Fonts for Unicode.)

For example, you might say this css:

body {font-family:"Arial Unicode MS","DejaVu Sans",sans-serif}
pre {font-family:"DejaVu Sans Mono",monospace}
