javascript - About unicode emoji expression issues

Question

This is a unicode encoding table found

http://www.fuhaodq.com/biaoqingfuhao/1531.html

Just take the first sun \ue04a

Output in the console \ue04a What I get is garbled characters

Then I found a 4-byte unicode, but the console output \ud83d\ude1d worked.

Why \ue04a cannot be parsed correctly? ? They are all according to the coding table.

Answer 1

The font you are using does not contain the complete unicode character set, please change it to another font
