[V11] Update body error if data contains Unicode characters

[nghiepdev]

Describe the bug

• Node.js version: 18, 20
• Got version: 11.8.6
• Related: Update body after beforeRequest #1453

Actual behavior

When replacing body in beforeRequest hook with a data that contains Unicode characters, an error may occur.

Code to reproduce

https://codesandbox.io/p/sandbox/hungry-dew-gd283f?file=%2Fapp%2Fpage.tsx%3A18%2C13-18%2C69

got
    .post("domain.api", {
      hooks: {
        beforeRequest: [
          (options) => {
            const newJsonBody = {
              ...options.json,
              new_field: "new_field",
            };

            // Original: not working
            options.body = JSON.stringify(newJsonBody);

            // Fixed
            // options.body = Buffer.from(JSON.stringify(newJsonBody));

            options.headers["content-length"] = options.body.length.toString();
          },
        ],
      },
      json: {
        city: "Hà Nội", // Unicode characters
      },
    })

Solutions

I found a solution by using a Buffer instead. It may be useful to update the documentation to reflect this approach.

Checklist

• I have read the documentation.
• I have tried my code with the latest version of Node.js and Got.
