APL Font

Default Font

The default APL font for the site is SImPL medium, SImPL, or APL385 Unicode.

If the APL characters in the articles don't display correctly, you can obtain a copy of the SImPL medium font by downloading the current NARS2000 binary, or the SImPL font from here, or the APL385 Unicode font from here.

If they still don't display correctly, download FireFox.

Extra APL Glyphs

While any Unicode APL font will display all of the standard APL glyphs, NARS2000 uses (or has plans to use) some extra glyphs not found in all Unicode APL fonts such as
