Identify double byte character in a string and convert that into a single byte character

Question

In my Go project, I am dealing with asian languages and There are double byte characters. In my case, I have a string which contains two words and there is a space between them.

EG: こんにちは　世界

Now I need to check if that space is a double byte space and if so, I need to convert that into single byte space.

I have searched a lot, but I couldn't find a way to do this. Since I cannot figure out a way to do this, sorry I have no code sample to add here.

Do I need to loop through each character and pick the double byte space using its code and replace? What is the code I should use to identify double byte space?

Answer 1

Just replace?

package main

import (
    "fmt"
    "strings"
)

func main()  {
    fmt.Println(strings.Replace("こんにちは　世界", "　", " ", -1))
}

Notice that the second argument in Replace is 　, as copy-paste from your string in example. This replace function will find all rune that match that in the original string and replace it with ASCII space
