How can I display the degree symbol in temperature indicators in my game’s user interface in Unity?

Displaying the Degree Symbol in Unity’s UI

Using GUILayout.Label or TextMesh for Degree Symbol

In Unity, you can easily incorporate the degree symbol into your UI elements like GUILayout.Label or TextMesh. Here is a step-by-step guide:

1. Directly Embedding the Degree Symbol

• You can directly embed the degree symbol (°) into your string:

  GUILayout.Label("Temperature: 25°C");

  This approach is straightforward when your text editor supports the symbol or when you’re hardcoding the value.

2. Using Unicode Values

• If embedding directly isn’t an option, use the Unicode value for the degree symbol:

  GUILayout.Label("Temperature: 25" + "\u00B0" + "C");

  This method ensures consistent display across different platforms, including Android.

3. Utilizing Hex or ASCII Codes

• Hex or ASCII codes are another alternative:

  char degreeSymbol = (char)176; // For ASCII
  GUILayout.Label("Temperature: 25" + degreeSymbol + "C");

Considerations

Always verify the text encoding settings of your development environment and target platform. Unity typically defaults to UTF-16, which universally supports Unicode symbols.

Implementing in TextMeshPro

If using TextMeshPro, you can simply add the degree symbol as a character in the text string, benefiting from its rich text format support:

public TMPro.TextMeshProUGUI temperatureText;
void Start() {
    temperatureText.text = $"Temperature: 25°C";
}

Ensure that the TextMeshPro font asset includes the degree symbol or uses a fallback font that does.
