@spec next_combined_emoji(String.t()) :: :none | {String.t(), String.t()}

Retrieve next combined Emoji grapheme from the beginning of a string, also returning rest of the string.

Examples

The Emoji woman scientist 👩‍🔬 is a combined character, its codepoints are:

["👩", ZWJ, "🔬"], so it can be detected as:

iex> next_combined_emoji("👩‍🔬 -> woman scientist")
{"👩‍🔬", " -> woman scientist"}

If no combined Emoji character detected at the beginning, :none will be returned:

iex> next_combined_emoji("👨 :)")
:none
