Symbol Font.
Here is a gif snapshot of part of a page showing the the Greek alphabet.



Here is the same information given using 'Symbol' font, as rendered by your browser.

The Greek Alphabet:

Alpha A a
Beta B b
Gamma G g
Delta D d
Epsilon E e
Zeta Z z
Eta H h
Theta Q q

Iota I i
Kappa K k
Lambda L l
Mu M m
Nu N n
Xi X x
Omicron O o
Pi P p

Rho R r
Sigma S s
Tau T t
Upsilon U u
Phi F f j
Chi C c
Psi Y y
Omega W w

Do they agree? If so, you can read everything in this website without problems. If not, read on.

Some browsers, particularly Firefox 3, no longer support <FONT FACE="Font_name"> statements in the default configuration. The argument for removal of this functionality is that the statement is not HTML standards compliant. The decison however implies that many mathematical web pages produced before 2005, and websites locked in to older software, will need to be rewritten. There is a small problem in that it isn't going to happen for information which is no longer maintained, but it is presumably better to throw away an entire cultural heritage than it is to allow non-conformity.

An applet-driven solution to the problem is given at everything2.com. However, using Firefox on my Ubuntu Linux machine I find that when I close the browser and re-open it, the bookmarklet has disappeared.

For other possible solutions, see:

To solve the problem relating to the content available here, I need to rewrite the numerous articles using HTML escape characters ( &symbol_name; ) or Unicode characters. Various small programs exist to perform the character replacement operation, but letting them loose on my HTML requires a complete and extremely thorough proof read after the conversion. Since it takes several weeks just to read through everything here (the AC Theory article on its own is equivalent to about 110 sides of A4), it will take a while.
     A permanent (and preferred) solution is to convert to Unicode and then copy everything into OO Writer. I can then use the proper formatting offered by Writer, and the Math editor for complicated equations, and export everything to PDF. This should give protection against future software and language 'upgrades', and results in professional-looking documents. The process is however laborious, especially since online PDF readers tend to permit arbitrary resizing, and this requires an increase in the resolution of the graphics files if the final result is to look good.
     A fast and dirty solution, which does not give full standards compliance, but makes pages readable in Firefox 3, is to search through and replace all instances of Symbol font with HTML escape characters (where possible). This process is nearing completion. Those which have not yet been reworked are marked (s).

Shown below is the Greek alphabet using HTML escape characters:

The Greek Alphabet:

Alpha Α α
Beta Β β
Gamma Γ γ
Delta Δ δ
Epsilon Ε ε
Zeta Ζ ζ
Eta Η η
Theta Θ θ

Iota Ι ι
Kappa Κ κ
Lambda Λ λ
Mu Μ μ
Nu Ν ν
Xi Ξ ξ
Omicron Ο ο
Pi Π π

Rho Ρ ρ
Sigma Σ σ
Tau Τ τ
Upsilon Υ υ
Phi Φ φ
Chi Χ χ
Psi Ψ ψ
Omega Ω ω

You should be able to see this correctly using Firefox 3, but it may not work if your browser is very old.
