APL Characters

In theory, you should see APL characters even with "Arial". Well, almost. Truth is that the version of "Arial" Windows is coming with is not a Unicode font. There is a font "Arial Unicode MS" available on many machines, but this font comes with some versions of Microsoft Office and some versions of the Microsoft Publisher. This font is not free anyway.

In theory, there is no difference between theory and practice. In practice, there is. Furthermore, experience shows that some fonts are buggy: they contain most APL characters but not all.

So to be sure that you can see APL characters we suggest to install one of these fonts:

APLX Upright

If you have installed a desktop version of APLX (full or evaluation copy), you will have this font installed already.

The font can be downloaded from:

APL385 Unicode

If you have installed any version of Dyalog APL, you will have this font installed already.

The font can be downloaded from:

Other APL fonts

Note that fonts like "Dyalog Std", "Dyalog Alt", "Causeway" and many others are not Unicode fonts. Therefore, the APL wiki does not even try to use them: they won't work!

Browsers

Every modern Browser should be fine. I suggest the latest Firefox for best results.

If you use Internet Explorer, make sure that it is version 7 or better. Everything else is a nightmare. Even IE7 is known to cause problems on some ordinary systems, and nobody can explain why, or fix the problem.
