Early terminal fonts (like those on VT100 or IBM 3270) were hardware-defined. When Linux and BSD systems began implementing virtual consoles, developers needed a software-based font format that could mimic the predictability of hardware terminals while remaining editable by the user. fsme font

The FSME format answered this need. It was lightweight, stored glyphs as simple bitmaps (typically 8x16 or 9x16 pixels), and allowed a user to replace a single character—say, a poorly designed '@' or '#' —without rebuilding the entire kernel. A standard FSME font file is remarkably simple. Here are its core characteristics:
