/**
Set foreground color with [UIColor clearColor] in joined-emoji range.
Emoji drawing will not be affected by the foreground color.
@discussion In iOS 8.3, Apple releases some new diversified emojis.
There's some single emoji which can be assembled to a new 'joined-emoji'.
The joiner is unicode character 'ZERO WIDTH JOINER' (U+200D).
For example: 👨👩👧👧 -> 👨‍👩‍👧‍👧.
When there are more than 5 'joined-emoji' in a same CTLine, CoreText may render some
extra glyphs above the emoji. It's a bug in CoreText, try this method to avoid.
This bug is fixed in iOS 9.
