如何在golang中将’更改为？ [重复]

Suppose there are 1000 user record in the csv file while reading that file 700 user have in there Last name this sign ’ and I have to change that sign to ' using golang. Is there any technique or function for this Which solve my problem?

One thing is that while I print this ’ for example

package main

import (
  "fmt"
)

func main() {
  strVal := "O’max"
  for i:= 0; i< len(strVal);i++{
    fmt.Println(string(strVal[i]))
  }
}

Output is :-

O
â


m
a
x

You're challenging with unicode issue. The problem is that you iterate over bytes, but not over characters. At the same time, your unicode character ’ takes 3 bytes, that's why you have that output. In order to handle it correctly, you have iterate with rune, which will handle unicode bytes.

func convert(src string) string {
    var sb strings.Builder

    for _, el := range src {
        if el == '’' {
            sb.WriteString("'")
        } else {
            sb.WriteRune(el)
        }
    }


    return sb.String()
}

And then, where you need to convert, you have to call

strVal = convert(strVal)
