How do I tell Cloud Translation - Advanced to *not* translate something?

:   You can use the following HTML tags:

    - `<span translate="no"> </span>`
    - `<span class="notranslate"> </span>`

    This functionality requires the source text to be submitted in HTML
    (`mimeType` must be `text/html`). You can't selectively
    ignore segments when you send content as `text/plain`.

Why was a `style` attribute added to the translated text with
`text-align` and `direction` CSS properties?

:   This occurs when you include HTML with the requested text to be translated, and
    you are translating from a right-to-left to a left-to-right language, or
    from a left-to-right to a right-to-left language. The translation
    includes the HTML `style` attribute with the `text-align`
    and `direction` CSS properties to ensure that the translated text
    is oriented in the proper direction. For example, translating
    `<h2>Sample text</h2>` from English
    to Hebrew returns the following JSON:

    ```json
    {
      "data": {
        "translations": [
          {
            "translatedText": "\u003ch2 style=\";text-align:right;direction:rtl\"\u003e טקסט לדוגמה (דברים) \u003c/h2\u003e"
          }
        ]
      }
    }
    ```

I get an `HTTP 403` error when I call the API.

:   You might have an issue with your billing account (such as an expired
    credit card), or you might be exceeding your daily billable total or the
    number of characters per minute quota. You receive the `Daily Limit
    Exceeded` error if you exceeded the daily limit or the `User Rate
    Limit Exceeded` error if you exceeded the characters per minute
    quota.

    To view the billing status of your project, see [Verify the billing status
    of your projects](https://docs.cloud.google.com/billing/docs/how-to/verify-billing-enabled) in the Cloud Billing documentation.

    To view or change usage quotas for your project, visit the [Quotas
    page](https://console.cloud.google.com/iam-admin/quotas?service=translate.googleapis.com) in the Google Cloud console.

I sometimes get `HTTP 500 (Internal Errors)` response from the
API
:   This could happen if you submit text without the source language
    specified. If Google cannot determine the source language given the text
    (usually because the text is too short), we will return a 500. This situation
    can be fixed by specifying the source language explicitly.

Can I specify multiple target languages in one request?
:   You can supply up to ten target languages in a [batch request](https://docs.cloud.google.com/translate/docs/advanced/batch-translation.md.txt).
    If you aren't making a batch request, you can only specify a single target
    language with your request.

Is it possible to get multiple translations of a word?
:   No. This feature is only available via the web interface at
    [translate.google.com](http://translate.google.com)

For native PDF document translations, the output includes translated text
overlaid on the source text.
:   Cloud Translation isn't removing the underlying text, which results in
    shadow text. For more information, see [Translate documents](https://docs.cloud.google.com/translate/docs/advanced/translate-documents.md.txt#overlaid).

For scanned PDF document translations, translations don't work for pages
where the source text isn't oriented horizontally.
:   If text isn't horizontal, Cloud Translation cannot
    correctly parse the text to translate. You can enable automatic rotation
    so that text is oriented correctly before translation. For more information,
    see [Translate
    documents](https://docs.cloud.google.com/translate/docs/advanced/translate-documents#orientation).
