compile error due to non-ascii character

[Goodhao]

I am new to typescript. When I tried to use tsc index.ts to compile your code, I got errors like this:

node_modules/flo-bezier3/node/implicit-form/exact/get-implicit-form1-.d.ts:7:5 - error TS1131: Property or signature expected.

7 vₓ: number; ~

Maybe it is caused by non-ascii character in your code? How can I fix it?
