Your best bet is to not use non-standard fonts to begin with. If you must
use a font for a particular area of a page, try to place the text in a
graphic. That way the text will appear exactly as you want it. If you really
want a particular font in a site, try using the Web Embedding Font Tools
(WEFT) from Microsoft (
http://www.microsoft.com/typography/WEFT.mspx). This
adds information about font objects in a page. Note, this will only work
with IE users. There is not another option for non-IE users.
Bottom line, if you have a lot of text that you want a lot of users to read,
don't use non-standard fonts. Many people don't like reading non-standard
fonts as they are used to a particular set of them.
Hope this helps,
