How Can I Remove Accents from Strings in Go?

Removing Accents from Strings in Go

Problem

Converting accented characters into their non-accented equivalents has been a challenge for some Go programmers. An attempt to implement a function using the "code.google.com/p/go.text/unicode/norm" package in Go 1.4 proved unsuccessful.

Solution

As of April 2015, an alternative approach is available with the introduction of the "runes" package, which includes a "Remove" function specifically designed for this purpose.

Go 1.5/1.6 Update

Looking ahead, Go 1.5 or 1.6 will likely bring a new "runes" package with transformation operations. This will offer a simplified solution using the "Remove" function, as seen in the following example:

<code class="go">package main

import (
    "fmt"
    "transform"

    "github.com/kjk/runes"
    "github.com/kjk/runes/example_test"
)

func ExampleRemove() {
    t := transform.Chain(norm.NFD, runes.Remove(runes.In(unicode.Mn)), norm.NFC)
    s, _, _ := transform.String(t, "résumé")
    fmt.Println(s)

    // Output:
    // resume
}

func main() {
    ExampleRemove()
}</code>
