How to Convert ANSI Text to UTF-8 in Go?

Converting ANSI Text to UTF-8 in Go

In Go, all strings are stored in UTF-8 format. However, you might encounter situations where you need to convert ANSI text, which uses a different character encoding, to UTF-8. Here's how you can achieve this:

According to the Go language specification, all strings are handled as UTF-8 internally. Therefore, there is no need for explicit conversion. If you have a byte array representing ANSI text, you can simply use the following snippet to convert it to a Go string:

import (
    "bytes"
    "unicode/utf8"
)

func convertANSItoUTF8(ansiBytes []byte) string {
    reader := bytes.NewReader(ansiBytes)
    decoder := utf8.RuneReader(reader)

    var utf8String []rune
    for {
        r, size, err := decoder.ReadRune()
        if err != nil {
            break
        }
        utf8String = append(utf8String, r)
    }

    return string(utf8String)
}

This function uses the utf8.RuneReader function to iterate over the ANSI bytes and convert them to UTF-8 runes. The runes are then appended to a slice, which is finally converted to a UTF-8 string.

Note: This function assumes that the ANSI input is valid. If there are any invalid sequences, the behavior of the function is undefined.
