Go的[]rune 和 []byte的区别
[]rune 和 []byte源码
// byte is an alias for uint8 and is equivalent to uint8 in all ways. It is
// used, by convention, to distinguish byte values from 8-bit unsigned
// integer values.
type byte = uint8
// rune is an alias for int32 and is equivalent to int32 in all ways. It is
// used, by convention, to distinguish character values from integer values.
原来是
byte
表示一个字节,
rune
表示四个字节,那么就可以得出了结论了,来看一段代码,使用中文字符串
