Unicode is a character encoding standard that has widespread acceptance. Microsoft software uses Unicode at its core. Whether you realize it or not, you are using Unicode already! Basically, âcomputers just deal with numbers. They store letters and other characters by assigning a number for each one.
Each character in a string is defined by a Unicode scalar value, also called a Unicode code point or the ordinal (numeric) value of the Unicode character. Each code point is encoded by using UTF-16 encoding, and the numeric value of each element of the encoding is represented by a Char object.
