[Variation selectors](https://en.wikipedia.org/wiki/Variation_Selectors_(Unicode_block)) are FE00 to FE0F. 

Note that two overlap with CSS properties to control the same thing:
    U+FE0E (VARIATION SELECTOR-15) selects text presentation
    U+FE0F (VARIATION SELECTOR-16) selects emoji-style

We should include all characters with the `Emoji_Modifier` property, which are currently all in the ` Miscellaneous Symbols and Pictographs` block.

>From [UTR51](http://www.unicode.org/reports/tr51/#def_level1_emoji):

> The `Extended_Pictographic` property is used to customize segmentation (as described in [UAX29] and [UAX14]) so that possible future emoji `zwj` sequences will not break grapheme clusters, words, or lines.  Maybe `Extended Pictographic` property is a better category than `Emoji` property (it is a superset of the latter).

I think that should be taken into account when defining a range for this generic family.

Also from [UTR51 ED-14](http://www.unicode.org/reports/tr51/#def_emoji_flag_sequence):

> emoji flag sequence — A sequence of two `Regional Indicator` characters, where the corresponding ASCII characters are valid region sequences as specified by Unicode region subtags in [CLDR], with idStatus="regular" or "deprecated".
