MiniGUI creates a few system fonts to draw menu text, window caption, or other general items. MiniGUI at least creates two system fonts: one mono-space logical font for single-byte charset, and one mono-space logical font for multi-byte charset. For the multi-byte charset, the width of one multi-byte character should be equal to the width of two single-byte characters.
