Unicode is a standard first released in 1991 which covers most characters from all of the world's written systems.
It covers current and historical scripts, alphabets, symbols, emojis and non-printable codes for controlling and formatting.
At the time of writing it contains almost 150,000 characters and is continually being updated by the Unicode Consortium.
The characters are arranged in planes and blocks. The current blocks and links to the defined characters on the Unicode website are provided below.
