What is this?

[GameLord2011]

I have a custom config based off of if_tea and the last bit confused with this last bit:

{
      "type": "prompt",
      "alignment": "left",
      "segments": [
        {
          "properties": {
            "always_enabled": true,
            "template": "\u2570\u2500\ue285\uf105\uf197  "
          },
          "template": " ",
          "foreground": "#00BCF9",
          "type": "status",
          "style": "plain",
          "foreground_templates": [
            "{{ if gt .Code 0 }}#ef5350{{ end }}"
          ]
        }
      ],
      "newline": true
    }

Does anyone know what this does, and the reasons for it to appear?

I went through the codes in the template block and found that it comes out with this: ╰─

After some googleing i found that this is related to git in some way, but i don't see where this comes up anywhere.

It appears when the last executed command has an error.
