* Tests with Regional Indicator flags: these behave differently depending
* whether an emoji font is present, as ligated flags are edited as single
* characters whereas non-ligated RI characters act individually.
*
* For now, only rely on such an emoji font on OS X 10.7+. (Note that the
* Segoe UI Emoji font on Win8.1 and Win10 does not implement Regional
* Indicator flags.)
*
* Once the Firefox Emoji font is ready, we can load that via @font-face
* and expect these tests to work across all platforms.
