I followed your instructions but there was no allow web sites instead it said allow pages to choose their own fonts

Fonts like the Symbol font that map on the basic ASCII set may not work in Firefox.

It is best to always use the Unicode representation of characters to avoid font problems because in that case any font that supports those symbols can be used and it works on all platforms if you have a font that covers that Unicode range.

I used the code for Greek letters instead of the letter and using Symbol font. It works ok but now I have to change all the thousands of letters in my data to create that special unicode.

I used javascript/canvas to display my Greek letters. I used if (Mid(AA[x],5,6)=="a"){context.fillText(Left(AA[x],4) + "\u03B1" + Right(AA[x],30),1,12);} In other words I broke up the text data into sections where I could convert the letter in Mid(AA[x],5,6) to a Greek letter when it is time to display on the screen. That way the letter stays normal in the data section.
