With the prevalence of Unicode, many systems render APL legibly out-of-the-box. However, for a uniform appearance, the font should be designed with APL in mind.[1] This article lists some fonts that are suited for APL.

Historical anecdote

Using IBM's APL\360 required the use of the IBM 2741 or IBM 1050 printing terminal with an APL type ball. The APL2741 font is based directly on this type ball.
