Someone writing code using Unicode 8 found that the FITZPATRICK
modifiers are considered separate graphemes from what they modify. This
is surprising, and seems contrary to not only the concept of a grapheme
cluster, but the spirit of tr51 2.2.3 "A supported emoji modifier
sequence should be treated as a single grapheme cluster for editing
