Having trouble viewing the Symbols ?

The symbols we have gathered and put up are called Unicode characters. You can get more information from Unicode Org

Additionally Wikipedia has some good information as well.

If you're having trouble viewing the Symbols. for example you get long squares on your PC instead of the actual symbol, it's more than likely due to the fact that your computer does not have the proper fonts / characters installed.

To fix the problem, you'll need to:

• Configure your browser to use the fonts shown
• Install the fonts that cover the characters you need
