Node-Red 3 complains about me

[Fabios]

Although it's possible to use Unicode Character in variables names, I don't recommend it. My first language is Portuguese, which has a lot of accented characters, and I don't use them in variables. Many chances of technical problems, besides the typos; If it's already difficult without accents, imagine with them. And the colors are another help from Monaco editor, depends on the theme you are using. But in this case, the editor is not recognizing the Übers as a variable, that's why it's got a different color. Try to rename to Ubers and see the change. About themes : https://discourse.nodered.org/t/how-to-use-themes-with-monaco-editor/48310
