For better support for German, here's a modification on top of @eusonlito's script with the expected mappings of umlauts and ß (ä -> ae, ß-> ss, etc):

function slugify(text, separator) {
  text = text.toString().toLowerCase().trim()

  const sets = [
    { to: "a", from: "[ÀÁÂÃÅÆĀĂĄẠẢẤẦẨẪẬẮẰẲẴẶ]" },
    { to: "ae", from: "[Ä]" },
    { to: "c", from: "[ÇĆĈČ]" },
    { to: "d", from: "[ÐĎĐÞ]" },
    { to: "e", from: "[ÈÉÊËĒĔĖĘĚẸẺẼẾỀỂỄỆ]" },
    { to: "g", from: "[ĜĞĢǴ]" },
    { to: "h", from: "[ĤḦ]" },
    { to: "i", from: "[ÌÍÎÏĨĪĮİỈỊ]" },
    { to: "j", from: "[Ĵ]" },
    { to: "ij", from: "[IJ]" },
    { to: "k", from: "[Ķ]" },
    { to: "l", from: "[ĹĻĽŁ]" },
    { to: "m", from: "[Ḿ]" },
    { to: "n", from: "[ÑŃŅŇ]" },
    { to: "o", from: "[ÒÓÔÕØŌŎŐỌỎỐỒỔỖỘỚỜỞỠỢǪǬƠ]" },
    { to: "oe", from: "[΅]" },
    { to: "p", from: "[ṕ]" },
    { to: "r", from: "[ŔŖŘ]" },
    { to: "s", from: "[ŚŜŞŠ]" },

    { to: "y", from: "[ÝŶŸỲỴỶỸ]" },
    { to: "z", from: "[ŹŻŽ]" },
    { to: "-", from: "[·/_,:;']" },
  ]

  sets.forEach((set) => {
    text = text.replace(new RegExp(set.from, "gi"), set.to)
  })

  text = text
    .toString()
    .toLowerCase()
    .replace(/\s+/g, "-") // Replace spaces with -
    .replace(/&/g, "-and-") // Replace & with 'and'

    .replace(/-+$/, "") // Trim - from end of text

  if (typeof separator !== "undefined" && separator !== "-") {
    text = text.replace(/-/g, separator)
  }

  return text
}
