When displaying text such as Hello World, you should instead use a localization token like #menu.helloworld. This will automatically replace the text with the corresponding language set by the user when set on a Label, allowing you to easily support multiple languages.

Tokens

In UI, any displayed string that begins with a # will be recognized as a token, which means it will look for it's real value in the localization system.

Example

Filename: Localization/en/sandbox.json

{
  "menu.helloworld": "Hello World",
  "spawnmenu.props": "Models",
  "spawnmenu.tools": "Tools"
  "spawnmenu.cloud": "sbox.game",
}

Then it's as easy as doing the following:

<label>#spawnmenu.props</label>
