Unicode is a current text representation standard that defines all of the letters and symbols that are regularly used in digital and print media today. Unicode has risen to prominence as the de facto standard for recognizing characters in text in almost any language.

To insert a Unicode character, input the character code, then press ALT + X. To type a dollar sign ($), for example, type 0024, then press ALT, then X.

Unicode utilizes two types of encoding: 8-bit and 16-bit, depending on the data type of the data being encoded. The standard encoding format is 16-bit, which means that each character is 16 bits (2 bytes) large.

The sixteen-bit encoding variant is commonly represented as U+hhhh, where hhhh is the character’s hexadecimal code point.
