"The Unicode Standard defines a codespace: a set of integers called code points and denoted as U+0000 through U+10FFFF. The first two characters are always "U+" to indicate the beginning of a code point. They are followed by the code point value in hexadecimal. At least 4 hexadecimal digits are shown, prepended with leading zeros as needed. " - How many bytes are in unicode
