Since we are used to standardized English keyboards when using our computers, special characters of various origin can be difficult to present. The below table shows the HTML Decimal Code, Unicode Hexadecimal and Official HTML Name for characters categorized for ASCII Math and Science. ASCII stands for American Standard Code for Informational Interchange.
The below list includes HTML character codes for Math and Science, which are usually not found in the standard character set. Should you wish to produce any of the unique characters below from the ASCII Math and Science Library, use the respective codes when writing your HTML code.
In order to use these characters, simply place the unique character code where you’d like the character to appear. Codes as such play a key part in translation projects.
