Many of these special symbols are now widely supported in web browsers such as Firefox, Safari, Internet Explorer, etc. We have done some testing and have established the a list of "safe" symbols which you can find at the following link: </p> <blockquote> <a href="entities.html"><strong>Widely Supported HTML4 and Unicode Characters</strong></a> </blockquote> For those symbols which are not widely supported, authors should use the following graphic images of the characters: <h2><a name="not">Special Symbols Not Widely Supported</a></h2> <h3>Logical Symbols</h3> <table border="1"
