Golang八进制字符吕转utf

package main import ( "fmt" "regexp" "strconv" ) // 转换8进制utf-8字符串到中文 // eg: `\346\200\241` -> 怡 func convertOctonaryUtf8(in string) string { s := []byte(in) reg := regexp.MustCompile(`\\[0-7]{3}`) out := reg.ReplaceAllFunc(s, func(b []byte) []byte { i, _ := strconv.ParseInt(string(b[1:]), 8, 0) return []byte{byte(i)} }) return string(out) } func main() { s1 := "\346\200\241" // 字面量 s2 := `\346\200\241` // 原始字符串 fmt.Println("s1 =", s1) fmt.Println("s2 =", s2) // 转化 s2 s3 := convertOctonaryUtf8(s2) fmt.Println("s3 =", s3) }
