Optical glitch: In Germany, we have special characters called “Umlaut” such as ä ü ö. If a vendor name contains such characters, the Curve App replaces them by “?”.
I.e. the German vendor name e.g. “Hofbräuhaus” in the Curve App is displayed as “Hofbr?haus”.
Not the worst problem in the world, but not nice and probably easy to fix…
