" summary

Explains why '👩🏿‍🎤'.length equals seven: the glyph is a sequence of code points (female + Fitzpatrick skin-tone + \u200D zero width joiner + microphone) that become multiple 16-bit code units under UTF-16/UCS-2 so JavaScript string length and split behave unexpectedly. Shows use of string.prototype.normalize, the UTF-8 meta tag for pages, the Unicode planes (emoji live in astral planes since Unicode 6 in 2010), and the emoji proposal process (examples: skin tones in 8.0, person emoji in 12.1).
