In order to use non-English characters in the Text tool in Design 3D CX 7, you must first install the needed fonts for a particular language onto your PC. This will make them available for the Text tool.
Every language has its fonts installed on the PC. Some fonts such as MS UI Gothic, Batang and Arial Unicode MS can be downloaded free from the internet and easily intalled on Windows. Just navigate to folder options through control panel_Appereance and Personalization.
You can also bring Polish fonts from one Polish computer to another English computer or vice versa.
This works with Slovak, Czech, Polish, Swedish, French or any font from a European or Eastern European language.
