eighteen in one font

The eighteen in one font is a shortened version of the big GNU FreeFont (10MB). The eighteen in one font contain the ASCII and the Mathematical Alphanumeric Symbols Unicode block. The Unicode block of the Mathematical Alphanumeric Symbols consists of Latin and Greek letters and decimal digits. There are a total of 18 different real character sets in the Mathematical Alphanumeric Symbols Unicode block.

The table displays the letters and numbers of the Mathematical Alphanumeric symbols in plain text in the charset attribute UTF-8, HTML hexadecimal character entity code, HTML decimal character entity reference, and HTML named character entity references.

Also displayed are the HTML character entities codes of the HTML character entity hexadecimal reference (HTML Entity Code), HTML character entity decimal reference (HTML Entity Number) and HTML named character entity references (HTML Entity Name).

The HTML named, HTML decimal (dec) or HTML hexadecimal (hex) references are not needed to display the chars when a document is stored in UTF-8 and the charset attribute UTF-8 is set. With UTF-8 also copy & paste the chars works. The HTML entities references, in particular the HTML named entities, make it easier to write the chars because they are not present on the keyboard, but the letters and numbers for the HTML entities references codes already. The HTML hexadecimal reference codes consist of the Unicode numbers of the characters. The HTML named references display some characters differently in different browsers.
