How can I display the degree symbol when showing temperature effects in my game’s UI in Unity?

Displaying the Degree Symbol in Unity

When developing a game in Unity, presenting the degree symbol in UI components like TextMeshPro or GUILayout can be crucial for temperature effects. This requires proper encoding, as Unity needs to handle Unicode characters correctly. Here’s how you can do it:

Using Unicode

The most straightforward way to display the degree symbol is by using its Unicode equivalent. You can use it directly in your scripts like so:

string temperatureText = "Temperature: 25\u00B0C";

The \u00B0 is the Unicode escape sequence for the degree symbol. Applying this to a UI Text or TextMeshPro component will correctly render it.

Using HTML Entities

For more complex GUI elements, especially if you’re using web views or HTML-based elements, you might prefer HTML entities:

string temperatureText = "Temperature: 25°C";

This ensures the correct rendering of the degree symbol in environments that support HTML parsing.

Best Practices

• Ensure your build and editor are both set to UTF-8 encoding to handle Unicode characters effectively.
• Use TextMeshPro instead of the default Unity UI text components for better text rendering and UTF support.
• Test the UI on all target platforms to ensure consistent rendering across devices.
