[snowfluke]

What version of Bun is running?

1.2.4+fd9a5ea66

What platform is your computer?

Linux 5.15.167.4-microsoft-standard-WSL2 x86_64 x86_64

What steps can reproduce the bug?

Write a transpile.ts file:

const transpiler = new Bun.Transpiler({
  loader: "ts",
  target: "node",
});

Bun.file("./index.ts")
  .text()
  .then((buf) => {
    transpiler.transform(buf).then((res) => console.log(res));
  });

And a index.ts file:

let list = ["•", "-", "◦", "▪", "▫"];

What is the expected behavior?

it should transpile:

let list = ["•", "-", "◦", "▪", "▫"];

What do you see instead?

let list = ["â¢", "-", "â¦", "âª", "â«"];
