Basic Knowledge
What is Unicode
Unicode is an international standard that assigns a unique number (code point) to every character and emoji in the world. Numbers are represented as U+ followed by hexadecimal notation, such as "U+3042" (= あ).
Relationship between Code Points and Character Encoding
A code point is the number assigned to a character, while UTF-8 and UTF-16 are methods that convert that number into an actual byte sequence. The same character "あ" (U+3042) is stored differently depending on the encoding: 3 bytes in UTF-8 and 2 bytes in UTF-16.
