With a little bit of erlang magic:
iex> :erlang.binary_to_list << 0x1f517 :: utf8 >>
[240, 159, 148, 151]
I have a unicode library that examines code points. For example:
iex> Unicode.category << 0x1F49A :: utf8 >>
[:So]
iex> Unicode.properties << 0x1F49A :: utf8 >>
[[:emoji, :grapheme_base]]
Unfortunately the Regex module doesn’t support the Unicode character class [:So:]. Or any other Unicode character classes. I have another lib unicode_set that has some support for Unicode character classes. But regexes not yet - soon though.
