Renovate: semanticCommitType not applied correctly

[Roms1383]

What Renovate type are you using?
Renovate GitHub App

Describe the bug
Expect commit message from Renovate to contain emoji prefix as configured, which wasn't applied correctly

Did you see anything helpful in debug logs?
Job ID #70208446 : project config being correctly used from .renovaterc.

To Reproduce
Steps to reproduce the behavior:

1. Create repository with .renovaterc :

{
  ...,
  "semanticCommitType": ":arrow_up:",
  "semanticCommitScope": null,
  "packageRules": [
    {
      "updateTypes": [
        "lockFileMaintenance",
        "pin"
      ],
      "semanticCommitType": ":pushpin:"
    },
    {
      "updateTypes": [
        "rollback"
      ],
      "semanticCommitType": ":arrow_down:"
    },
    {
      "updateTypes": [
        "digest",
        "bump"
      ],
      "semanticCommitType": ":bookmark:"
    }
  ]
}

1. Wait next PR opened by RenovateBot to upgrade dependencies

Expected behavior
e.g. with PR Update dependency @commitlint/cli to v8
I would have expected the commit message to be :
⬆️Update dependency @commitlint/cli to v8
Instead I got :
Update dependency @commitlint/cli to v8

Additional context
I heavily rely on these semanticCommitType to be applied correctly, as I use a special preset for semantic-release based on gitmoji.

Are you extending any of Renovate’s other presets?

[Roms1383]

No, I just use this .renovaterc only.

[Roms1383]

It follows our former discussion here :)

[rarkins]

Can you replicate this in a public repo with similar config? That will make it a lot faster to debug

[Roms1383]

Yes : https://github.com/Roms1383/test-renovate

[Roms1383]

I also added you as a collaborator on the repo in case you want to process some additional tests 👍

[rarkins]

I worked out the problem, but perhaps it now uncovers a new one. The ⬆️ symbol is not being translated in the title in my test repo:

Is that expected?

[Roms1383]

Yes => :arrow_up:

[Roms1383]

The only thing that matters for semantic-release is :arrow_up: (or other emoji code), then usually Github display it with a nice symbol like ⬆️ (which is just formatted on display)

[rarkins]

Strange thing is that GitHub isn't formatting it nicely for me when I test.

Anyway, the solution is to add this config: "semanticCommits": true. I also released a patch 18.7.2 that makes sure you don't end up with two semicolons in a row.

[Roms1383]

That's awesome, thanks !

[Roms1383]

One last thing @rarkins : can I delete the test repository ?

[rarkins]

Yes go ahead
