Unify – Unicode support on browsers and devices

Some excellent research for web developers: find out which unicode characters have the widest support—release useful for choosing icons.

While doing some browser testing this week, Mark come across a particularly wicked front-end problem. Something was triggering compatibility mode in Internet Explorer 8 and he couldn’t figure out what it was.

Compatibility mode was something introduced in IE8 to try not to “break the web”, as Microsoft kept putting it. Effectively it makes IE8 behave like IE7. Why would you ever want to do that? Well, if you make websites exactly the wrong way and code for a specific browser (like, say, IE7), then better, improved browsers are something to be feared and battled against. For the rest of us, better, improved browsers are something to be welcomed.

Shockingly, Microsoft originally planned to have compatibility mode enabled by default in Internet Explorer 8. It was bad enough that they were going to ship a browser with a built-in thermal exhaust port, they also contemplated bundling a proton torpedo with it too. Needless to say, right-minded people were upset at that possibility. I wrote about my concerns back in 2008.

Microsoft changed their mind about the default behaviour, but they still shipped IE8 with the compatibility mode “feature”, which Mark was very much experiencing as a bug. Something in the CSS was triggering compatibility mode, but frustratingly, there was no easy way of figuring out what was doing it. So he began removing chunks of CSS, reducing until he could focus in on the exact piece of CSS that was triggering IE8’s errant behaviour.

Finally, he found it. He was using an icon font. Now, that in itself isn’t enough to give IE8 its conniptions—an icon font is just a web font like any other. The only difference is that this font was using the private use area of the unicode range. That’s the default setting if you’re creating an icon font using the excellent icomoon service. There’s a good reason for that:

Using Latin letters is not recommended for icon fonts. Using the Private Use Area of Unicode is the best option for icon fonts. By using PUA characters, your icon font will be compatible with screen readers. But if you use Latin characters, the screen reader might read single, meaningless letters, which would be confusing.

Well, it turns out that using assigning glyphs to this private use area was causing IE8 to flip into compatibility mode. Once Mark assigned the glyphs to different characters, IE8 started behaving itself.

Now, we haven’t tested to see if this is triggered by all of the 6400 available slots in the UTF-8 private use range. If someone wants to run that test (presumably using some kind of automation), ’twould be much appreciated.

Meantime, just be careful if you’re using the private use area for your icon fonts—you may just inadvertently wake the slumbering beast of compatibility mode.

❍ IcoMoon

This is a great free service for generating small subsetted icon fonts. Launch the app and have a play around — you can choose from the icons provided or you can import your own SVG shapes.

Nice touch: you can get the resulting font (mapped to your choice of unicode characters) base-64 encoded for your stylesheet.

Daniel recently asked a question on Twitter:

I vaguely recall someone (@lukew?) posting examples of ‘open nav’ icons (eg Path and Facebook) showing an emerging de facto standard. Link?

It was this article by Malarkey that he was looking for. Andy did a great job of comparing the iconography used for navigation in mobile apps and responsive sites. His conclusion:

Unless our navigation’s arranged in a grid (and so we should use a grid icon), I’m putting my weight behind three lines because I think it’s most recognisable as navigation to the average person.

The three-lines icon is certainly very popular, as can be seen in this collection of mobile navigation icons I gathered together on Dribbble.

But Tom has some reservations:

@dburka @adactio @malarkey I’m a bit suspicious of the three lines thing when not in a clear button though. Looks like a drag affordance

Andy Davies points out another potential issue:

@sunpig @adactio Chrome canary is now using the triple line for the menu toolbar button twitter.com/andydavies/sta…

— Andy Davies (@andydavies) August 9, 2012

I noticed this in the more recent versions of Android too. It does indeed look a little odd to see the same icon used in the browser chrome and in the document within the browser.

But I still think it’s a good shorthand for revealing a list of items.

The unicode character ☰ ☰ (U+2630) is the Chinese trigram for sky (or heaven)—one of the eight bagua. It consists of three horizontal lines. Now that could be a handy resolution-independent way of representing navigation.

Alas, when I tested this on a range of mobile devices, some of them just showed the square box of unicode disappointment. I had much better luck with the unicode symbol for black down-pointing triangle ▼ ▼ (U+25BC).

Mind you, with a combination of @font-face and sub-setting we’re not limited to what the browser ships with—we can provide our own icons in a font file, like what Pictos is doing.
