golang string和[]byte的对比

以下所有观点都是个人愚见，有不同建议或补充的的欢迎emial我aboutme何为string？什么是字符串？标准库builtin的解释：type string string is the set of all strings of 8-bit bytes,conventionally but not necessarily representing utf-8-encoded text. a stringmay be empty,but not nil. values of string ...

golang 中获取字符串个数

golang 中获取字符串个数在 golang 中不能直接用 len 函数来统计字符串长度，查看了下源码发现字符串是以 utf-8 为格式存储的，说明 len 函数是取得包含 byte 的个数 string is the set of all strings of 8-bitbytes,conventionally but not necessarily representing utf-8-encoded text. a stringmay be empty, ...

Unicode 和 UTF-8

ascii codesas you can infer from the above table,the ascii values can be represented from 0 to 127 in the decimal numbersystem. lets look at the binary representation of 0 and 127 in 8 bit bytes.通过上表我们得知，通过0到127可以代表ascii值任意值，让我们看一下如何通过的8位的二进制来表示0到127...
