The issue is limited to the Microsoft Teams classic desktop client. Gatus alert cards are rendered correctly on my phone Teams App and on the web client via Office 365.

Here is the emoji on the MessageCard Title https://www.iemoji.com/view/emoji/865/travel-places/police-car-light

And here it is in Hexadecimal (🚨)

I've also experienced this problem, it started when I updated teams a few weeks ago 😞

I'm not using the "Try the new Teams" feature although the same issue exists when I turn it on

I think color code needs to be changed (https://github.com/TwiN/gatus/blob/de7256e671c3cc6106a154a8fd49df426f4ce56a/alerting/provider/teams/teams.go#L108), not sure

I don't know what side is wrong on this since other similar tools also got broken notifications...

This topic was recently reported at Microsoft at https://techcommunity.microsoft.com/t5/microsoft-teams/new-teams-unicode-hex-character-and-emoji/m-p/3963936 google also show up earlier similar issues...

Both flavours of Teams (traditional and "new") are affected according to my experience.

To be completely honest, that seems more like an issue with Microsoft Teams than with Gatus, however, it's an issue nonetheless.

If allowing the customization of the title in the message generated by the webhook payload sent by Gatus resolves the situation, then I'd be willing to add a new alerting.teams.title field.

There's already a precedent for this anyways: see #602, which was made for Discord's title to be customizable.

@TwiN sounds like a new feature. thanks
