I'm changing my pages to Unicode, because Windows and SPIonic don't work at all well together in the latter versions of IE. Either the display is bad, or the printing, or even both.

I have made one CSS style sheet for all of my pages where I specify a series of Unicode fonts (see lower down on this page). You'll need one of them. If you have several of that list installed, your browser will use the first one it finds on your computer. Even if you would prefer a different one. If you don't like it, just remove it, and install one you like better.
Or instruct you browser to "ignore font styles specified on the web", under: Tools-Internet Options-General-Accessibility. You must then also specify which Unicode font you want to see: Tools-Internet Options-General-Fonts)

Why have I done that, instead of letting you use your default font automatically, without going through the "Accessibility" option?
Again because of IE. While Netscape, Mozilla, Firefox, Opera have no trouble displaying a Unicode page properly, IE seems not to know what to do with diacritics. Unless it is told what font to use. So that's what I have done. In the following order:

 Arial Unicode Ms, Palatino Linotype, Lucida Grande, Titus Cyberkit Basic, Alkaios, Cardo, Vusillus Old Face, Tahoma  

I have put Tahoma last because, although it is supplied as a good Unicode font with Windows XP, the earlier version which is supplied with the other Windows, is not. But your browser wouldn't know that and would therefore use it, with disastrous effects: no diacritics but little blank boxes.
