  This problem can be solved easily by selecting the default font. Please select the tab "Fonts", via the main menu, "SimpleMind" - "Preferences". Change all fonts back to the default font. Or select for all fonts:
  • Simplified Chinese: Microsoft Yahei
  • Traditional Chinese: Microsoft JhengHei
  • Japanese: Meiryo
  • Korean: Batang
Other fonts may work as well.
