unicode-range tests returns false negative on firefox beta in linux

[ryanseddon]

Firefox beta (v38) now supports unicode ranges that doesn't require enabling a flag.

Our unicode test returns a false negative because linux doesn't have arial and fallsback to the monospace font.

so, layout.css.unicode-range.enabled is actually false in Firefox 38 in sauce. But is is true in firefox 39.

In addition, the caniuse tests actually seem to be failing in firefox 39. I think this may actually be a false false negative

Firefox 39 does support unicode-ranges but i think it has bugs. However this issue will still false negative in FF40 on linux due to the nature of the test using a font that doesn't exist on linux.

firefox 38 had unicode-range enabled as well. it seems that it is enabled on dev and disabled later on down the release train.

"arial" doesn't really mean arial. in actually loads Liberation Sans on (most) linux if you were to set it to set its font property directly. This is one of the reasons its a "web safe" font.

Our test is failing in firefox 40, but so is every unicode-range demo I can find (including caniuse).

But that's not the case in FF aurora (v39) our test works and passes support on windows & osx but not on linux because arial isn't on there. So the test renders all characters in monospace.

Set arial as the font-family on the Linux browser before unicodeRange
