Emojis not supported in tags

[grod220]

Describe the bug
Whenever an emoji is used, it does not write tags properly.

To Reproduce

exiftool.write(`myfile.jpg, {
  Description: '🦍 hello world',
});

This will produce a new file with the field written as ?????? hello world. I believe it is corrupting the field.

Expected behavior
Expected the field to save the emoji character.

Environment (please complete the following information):

• OS and version: Mac OS X Catalina
• Node.JS version: v15.0.1

Thanks for the report!

FWIW, "simple" emoji are supported, but compound emoji are not currently. I'll fix this now.

  1) WriteTask
       round-trip with an image
         round-trips a comment with an emoji:

Crap: it's because of my home-grown html entity encoder (that I wrote to avoid external dependencies). If I switch it out for he, everything works.

he is used by 4.2 million projects, and it only adds 73.8 kB, so I think that's the better solution.

I'm publishing the fix now.

Thanks again for the bug report!
