Garbage Characters?
These pages use standard Web characters (Unicode) for mathematical symbols like less than or equal to (≤), pi (π), minus (−), alpha (α), theta (θ), f-prime (f′), square root (√), infinity (∞), and y-hat (ŷ). Even if you’re still using Windows 95 and a 4.x-level browser, you should be able to view all the characters used on these pages. It’s just a matter of configuring Windows and your browser properly, and perhaps getting hold of a suitable (free) font, as explained below. Two pages let you test your browser with a variety of characters: • Andreas Prilop’s Mathematical formulas in HTML 4.0 (link verified 2008-10-05) focuses mostly on math characters. • Alan Wood’s Using Special Characters from Windows Glyph List 4 (WGL4) in HTML (link verified 2008-10-05) is more systematic and lists many more characters.
