In order to make APL ghyphs appear in a web site you have three
choices:
1. Use a browser with a default font that contains all the APL
glyphs.
Strangely I am not aware that any other browser than Safari on the
Mac
(but NOT under Windows) gets this right. It might look ugly, but you
might see the APL characters.
2. Rely on a certain font installed on your machine / device.
It seems that Dyalog's tutorial is doing this, but I might be wrong:
the source code of the HTML pages is practically unreadable, and the
CSS is extremely verbose.
3. Rely on modern browsers which can download and install temporarily
a font requested by a web site. That's the approach chosen by Vector
and the APL Wiki. It's perfect but fails with old Browsers (IE6 for
example).
Your personal page explicitly declares itself as "windows-1252" which
means no Unicode. I can see APL chars, but I have no idea why. In
any case you rely on what the Browser is doing. You may or you may
not
see APL characters. If you do you are very lucky.
When you go to the APL Wiki with your Android device, do you see APL
chars?
