Benchmark: Diacritics removal

Script Preparation code:

const replaceMap = {
    œ: 'oe',
    æ: 'ae',
}
const replacementsRegex = new RegExp(Object.keys(replaceMap).join('|'), 'g')
window.removeDiacritics = (value) => {
    return value
        .normalize('NFD')
        .replace(/[\u0300-\u036f]/g, '')
        .replace(replacementsRegex, (char) => {
            return replaceMap[char] || char
        })
}

window.oldRemoveDiacritics = function(s) {
    if (!s)
        return s;

    let r = s;

    r = r.replace(/[àáâãäå]/g, 'a');
    r = r.replace(/æ/g, 'ae');
    r = r.replace(/ç/g, 'c');
    r = r.replace(/[èéêë]/g, 'e');
    r = r.replace(/[ìíîï]/g, 'i');
    r = r.replace(/ñ/g, 'n');
    r = r.replace(/[òóôõö]/g, 'o');
    r = r.replace(/œ/g, 'oe');
    r = r.replace(/[ùúûü]/g, 'u');
    r = r.replace(/[ýÿ]/g, 'y');
    r = r.replace(/\\W/g, '');

    // To prevent some weird behaviors with MacOS diacritics
    r = _(r).map(function(char) {
        return String.fromCharCode(char.charCodeAt(0));
    });

    return r.join('');
};
