The relationship between bits, bytes, characters and Chinese characters

1 bit binary data 1 byte = 8 bit
1 letter = 1 byte = 8 bit
1 kanji = 2 byte = + bit

1. bit: Bits
One binary data 0 or 1, is 1bit;

2. byte: Byte
1 byte = 8 bit

3. An English character occupies one byte;
1 letter = 1 byte = 8 bit

4. a kanji account of 2 bytes;
1 Kanji = 2 byte = + bit

(This is not necessarily correct, depends on the encoding type)

5. punctuation
A>. The input state of Chinese characters, the default is full-width input mode;
B>. In the English input state, the default is the half-width input mode;

C>. In full-width input mode, punctuation is 2 bytes;
D>. In the half-angle input mode, punctuation marks account for 1 bytes;

Therefore: characters in the input state of the characters, accounting for 2 bytes (but do not exclude, they changed the default settings);
The characters in the English input state, accounting for 1 bytes (but do not exclude, they changed the default settings);
