Please remove Byte Order Mark returned from drive's `export` in `'text/plain'` format

1. Is this a client library issue or a product issue?

Client library issue

2. Did someone already solve this?

no

3. Do you have a support contract?

no

Environment details

• OS: Linux 5.4 Ubuntu 18.04.5 LTS (Bionic Beaver)
• Node.js version: 14.4.0
• npm version: 6.14.5
• googleapis version: 61.0.0

Steps to reproduce

1. Make a create request, using for the body a string that does not begin with a Byte Order Mark and a mimeType of 'text/plain', such as

const requestBody = {
  name,
  parents: [folderId],
  mimeType: 'application/vnd.google-apps.document',
};
const media = {
  mimeType: 'text/plain',
  body: 'foo', // <--- This string doesn't have a BOM.
};
const data = await drive.files.create({
  requestBody,
  media,
  fields: 'id',
});

2. Make an export request of the previously created file with the mimeType set to 'text/plain', such as

const { data } = await drive.files.export({
  fileId: id,
  mimeType: 'text/plain',
});

3. The value data.content will contain a string that starts with a Byte Order Mark, "\uFFEFfoo", which was not in the original string.

Being the BOM an invisible character, it is increadibly hard to spot. This makes tests and application code harder to develop.

Hi @aryzing, I've been able to confirm this is occurring. Thanks for submitting.

This client library is auto-generated, and this issue is actually an underlying issue with the API itself, not with this library. Therefore, I've gone ahead and created a bug with the API that you can follow along here.
