You can use the OS/2 Font Editor to design and save your own fonts for use in applications.
A font is a set of alphanumeric characters, punctuation marks, and other symbols that share a common typeface design and line weight. An application loads a font from a dynamic-link library file (.DLL file).
The Font Editor allows you to edit an enlarged version of each character in an editing window, using the mouse to switch the enlarged representation of pels to black or white.
You can change a series of pels by dragging the mouse pointer through them while holding down the mouse button. An enlarged scale version of the character is shown in a viewing window to the right of the edit window.
