一个字符中有多少位？ [英] How many bits in a character?

问题描述

我只是困惑...一个位有多少字符？

I'm just confused...just how many characters in one bit?

推荐答案

以及它所处的编码：

• 8位ASCII编码中的ASCII字符是8位

• An ASCII character in 8-bit ASCII encoding is 8 bits (1 byte), though it can fit in 7 bits.

ISO-8859-1编码中的ISO-8895-1字符是8位（1字节）。

An ISO-8895-1 character in ISO-8859-1 encoding is 8 bits (1 byte).

UTF-8编码中的Unicode字符介于8位（1字节）和32位（4字节）之间。

A Unicode character in UTF-8 encoding is between 8 bits (1 byte) and 32 bits (4 bytes).

UTF-16编码中的Unicode字符介于16（2字节）和32位（4字节）之间，但大多数常见字符需要16位。这是Windows内部使用的编码。

A Unicode character in UTF-16 encoding is between 16 (2 bytes) and 32 bits (4 bytes), though most of the common characters take 16 bits. This is the encoding used by Windows internally.

UTF-32编码中的Unicode字符始终为32位（4字节）。

A Unicode character in UTF-32 encoding is always 32 bits (4 bytes).

UTF-8中的ASCII字符为8位（1字节），并且为UTF-16 - 16位。

An ASCII character in UTF-8 is 8 bits (1 byte), and in UTF-16 - 16 bits.

ISO-8895-1（0xA0-0xFF）中的附加（非ASCII）字符在UTF-8和UTF-16中将占用16位。

The additional (non-ASCII) characters in ISO-8895-1 (0xA0-0xFF) would take 16 bits in UTF-8 and UTF-16.

这意味着有一点0.03125到0.125个字符。

That would mean that there are between 0.03125 and 0.125 characters in a bit.
