WebAug 2, 2010 · In Java and C#, a char is a UTF-16 code unit and thus a 16-bit type. But in Unicode, a character is represented by a "code" point that ranges from 0 to 0x10FFFF, for which a 16-bit type is inadequate. So a character must either be represented by a 21-bit type (in practice, a 32-bit type), or use multiple "code units". Specifically, WebOct 28, 2024 · In order to find out if the value is true or false at index i we need to create a bit mask from the bit index : 1 << bitIndex and than apply following expression: bitArray[byteIndex] & mask != 0.
