Unicode
I take a look at “whatisit":
⚠️
U+26A0 : WARNING SIGN
U+FE0F : VARIATION SELECTOR-16 [VS16] {emoji variation selector}
But even better: runes is CLI for exploring these emojis! Let’s install it:
go get github.com/mna/runes
Now, let’s see with an emoji that I know displays correctly in my terminal (iTerm2):
% runes - ✅
[S So] U+2705 '✅' [E2 9C 85] [2705] WHITE HEAVY CHECK MARK
[C Cc] U+0000 [00] [0] <control>
[C Cc] U+0000 [00] [0] <control>
Now, let’s try with my multi-UTF-8 example “⚠️”:
% runes - ⚠<fe0f>
[S So] U+26A0 '⚠' [E2 9A A0] [26A0] WARNING SIGN
[C Cc] U+0000 [00] [0] <control>
[C Cc] U+0000 [00] [0] <control>
[M Mn] U+FE0F '️' [EF B8 8F] [FE0F] VARIATION SELECTOR-16
[C Cc] U+0000 [00] [0] <control>
[C Cc] U+0000 [00] [0] <control>
My terminal (iTerm2) doesn’t even allow me to paste “⚠️”?! It shows ⚠<fe0f> instead.
