Renovate warns about Unicode non-breakable space

[nijel]

How are you running Renovate?

A Mend.io-hosted app

Which platform you running Renovate on?

GitHub.com

Which version of Renovate are you using?

43.235.0

Please tell us more about your question or problem

We're using Unicode non-breakable space (0x00A0) in some of our files and this now produces quite alerting message:

Is there a way to tell Renovate that this is actually okay? I could not find any related settings in the documentation.

Is it actually expected to complain that text files not processed by Renovate use non-breakable space?

Logs (if relevant)

Logs

WARN: Hidden Unicode characters have been discovered in file(s) in your repository. See your Renovate logs for more details. Please confirm that they are intended to be there, as they could be an attempt to "smuggle" text into your codebase, or used to confuse tools like Renovate or Large Language Models (LLMs)

  "file": "...",
  "hiddenCharacters": "\\u00A0"
}

Is it actually expected to complain that text files not processed by Renovate use non-breakable space?

No, I think it only complains about the file it has processed. If that is not the case, please create a minimal reproduction for it and I'll debug further.

This happened on https://developer.mend.io/github/WeblateOrg/wllegal, for example https://developer.mend.io/github/WeblateOrg/wllegal/-/job/019f0304-21e4-7817-88a4-f51cef2ad4a7:

{
  "file": "wllegal/templates/legal/documents/privacy.html",
  "hiddenCharacters": "\\u00A0"
}

I didn't notice this until recently, and these files haven't substantially changed for a few years, so it might be some recent change (or I simply didn't notice for a long time).

I will look into a minimal reproducer later.

…and now when I got to look into reproducing, the warning is gone. The renovate version on both runs is 43.242.2.

Hi there,

Please help this Discussion progress by creating a minimal reproduction. This means a repository dedicated to reproducing this issue with the minimal dependencies and config possible.

Before we start working on your issue we need to know exactly what's causing the current behavior. A minimal reproduction helps us with this. Discussions without reproductions are less likely to be converted to Issues.

Please follow these steps:

1. Read our guide on creating a minimal reproduction.
2. Go to our minimal reproduction template repository.
3. Select the Use this template button to create a new repository based on the template.
4. Work on the reproduction in your own repository. Ensure it's actually minimal (no unnecesary dependencies or config), or it will be rejected by maintainers.
5. Install the Renovate app to verify that what you say happens (or doesn't happen) reproduces.
6. Fill out the information in your repository's README.md. What you describe there should reflect what you see in this repo, with the hosted app, and not what you saw in your original repo/environment.
7. Add the link to your reproduction to the first post of your Discussion. If you are not the original author, you can post a new comment with the link.
8. Add a Discussion comment mentioning that the reproduction repo is now available and linked.

If you need help with running Renovate on your minimal reproduction repository, please refer to our Running Renovate guide.
Good luck,

The Renovate team
