The Unicode entity:

U+2714 HEAVY CHECK MARK

Has different encodings:

• UCS4: 0x00002714
• UTF-16: 0x2714
• UTF-8: 0xE2 0x9C 0x94
• HTML Entity: ✔

And that is all well and good. And if you have a Unicode file with that encoded character:

00000000: FF FE 14 27

And if put that second style, the Emoji style, into a text file:

Offset    00 01 02 03 04 05
00000000: FF FE 14 27 0F FE

it renders in a browser as HEAVY CHECK MARK but this time in Emoji style:
