This is because on most operating systems, a char maps well to one byte.
这是因为在大多数操作系统上，一个字符能很好地映射成一个字节。
CHAR Stores single-byte or multibyte text strings of fixed length (up to 32,767 bytes); supports code-set order in collation of text data.
CHAR存储固定长度的单字节或多字节的文本字符串(最高可达32,767个字节)；在整理文本数据时支持使用代码集顺序。
This means that if a char variable is defined, it will consume no more than a byte (8 bits).
这意味着，如果定义一个char变量，它占用的空间不会超过一字节(8位)。
So a char is one byte, which is bits — how many?
所以char类型占了1个字节，——那是多少位？
Malloc It returns the address of this first byte so really the address of the first char here and so what gets stored in s2 now?
返回的是什么？，What, does,malloc, return ？，它返回的是第一个字符，第一个字节的地址，现在在s2中存储的是什么？
The first byte overlaps with the char member; the last doesn't.
第一个字节与字符成员是重叠的；最后一个字节则没有重叠。
In particular, there is no support for searching for exact strings and failing fast, and the engine requires us to transform our byte -strings to char or string.
具体地说，它不支持对字符串的精确查找，不支持fail -fast，而且该引擎要求我们把byte字符串转换成char或者String。
Vector Pointers, since the value they point to is 16-bytes long, move forward in increments of 16 bytes, while char Pointers move forward in single-byte increments.
由于向量指针所指向的值是16字节长的，因此会按照16字节的单位来移动；而char指针则是按照1个字节的单位来移动的。
If those all fail, it looks for foo (short), foo (char), and foo (byte).
如果全部失败，它会查找foo (short)、foo (char)和foo (byte)。
So a char size is 1 byte or 8 bits.
一个char型数据占据1字节或8比特。
Byte indicates that the column will have byte length semantics. Char indicates that the column will have character semantics.
BYTE代表该列以字节计算长度，CHAR代表该列以字符计算长度。
Unable to convert Multi Byte string to Wide Char String. The script could not be parsed.
无法将多字节字符串转换为宽字符字符串。无法分析该脚本。
The unsigned char data type, and byte data type will yield incorrect results and act as though they are signed types i. e. type char.
无符号字符数据类型和二进制数据类型将产生错误的计算结果，会当成有符号的数据类型进行计算。
