+public static String slugify(String text, String separator) {

+        return "";
+
+    // used to decompose accented characters to their base characters (e.g. "é" to "e")
+    String normalizedString = Normalizer.normalize(text, Normalizer.Form.NFD);

+    String slug = normalizedString.trim()
+            .toLowerCase()
+            .replaceAll("\\s+", separator)

+// Usage:
+System.out.println(slugify("Hello World-#123-é", "-")); // "hello-world-123-e"
