Character Codes for html

I'm not an expert on this, but here's what I've learned so far... I've compiled a list of commonly used symbols and their usage in html files

For more Windows' encodings, check out -> start menu -> programs -> accessories -> system tools -> character map

what you'll probably need to view all the encodings here:

1) the fonts OpenSymbol which is a true type font, and Symbol which is open type. You can download the fonts if you want, but note that these two fonts only encodes all the mathematical symbols here. For the Latin symbols only, there should be no need to download anything.
2) these encodings are best viewed with the later versions of Internet Explorer or Netscape, not Opera though.

how to use:

I've made a table to look like this: Symbol - Name of Symbol - html code (in the case where there are no html code, just cut and paste the symbol itself). So, say you want the symbol ≈ in your html file, then you'll cut and paste &#8776 in your html file, don't cut and paste ≈, because nothing will show up when you load up your html file.
