Invalid or unexpected token

[LukeTOBrien]

🐛 bug report

I am getting the following:

Uncaught SyntaxError: Invalid or unexpected token 

The line in question:

var th=basePropertyOf({À:"A",�:"A",Â:"A",Ã:"A",Ä:"A",Å:"A",à:"a",á:"a",â:"a",ã:"a",ä:"a",å:"a"...

These are unicode and I don't know why they are being produced.

Hello,

I found this post on the Terser repo: terser/terser#1005
I then added the following to my .terserrc and it seems to have solved the issue:
(It is still really strange)

"format": {
        "ascii_only": true
    }

I must say that I am confused around the area of minification.
Your documentation says:

Parcel uses SWC to minify JavaScript

But then it says:

you can configure these tools using a .terserrc

So is Parcel using SWC or Terser?
The sentence says SWC but we are using terser configuration?

I think the documentation can be improved by explaining more and making it clearer.
