What are the differences between Bitmap and True-Type fonts in ZTERM?
ZTERM’s terminal emulation window can use either a special bitmap font designed for use with ZTERM or any monospaced True-Type font. The preferable mode is to use the bitmap font, especially when dealing with applications that switch in and out of 132 column mode. The bitmap fonts are specifically designed to scale between 80 and 132 column modes while maintaining the same character height. If you use a True-Type font, switching between these modes will result in the character height changing, which can lead to difficulties in reading the display.
