Golang remove accents

remove_accents.go

package main

import (
        "fmt"
        "unicode"

        "golang.org/x/text/transform"
        "golang.org/x/text/unicode/norm"
)

func isMn(r rune) bool {
        return unicode.Is(unicode.Mn, r) // Mn: nonspacing marks
}

func main() {
        s := "Yoùr Śtring šđč枊ĐČĆŽ Ötzi's Nationalität èàì"
        b := make([]byte, len(s))

        t := transform.Chain(norm.NFD, transform.RemoveFunc(isMn), norm.NFC)
        _, _, e := t.Transform(b, []byte(s), true)
        if e != nil {
                panic(e)
        }

        fmt.Println(string(b))
}

nDst, _, e := t.Transform(b, []byte(s), true)
        if e != nil {
                panic(e)
        }

fmt.Println(string(b[:nDst))

otherwise there were some trailing x\00

Had to increase destination buffer size (length of the string is sometimes larger after this transform, which leads to "transform: short destination buffer" error)

I'm using this to rename files but I'm having trouble as it removes the . of the file.
Any suggestion?

A little late to the party but it looks like that function is now deprecated. You can use runes.Remove instead:

transform.Chain(norm.NFD, runes.Remove(runes.In(unicode.Mn)), norm.NFC)

sorry the Ñ is a not character accent in spanish

this works but takes the Ñ as an accent char so does not work in Spanish
