+   *
+   * It may fail to convert characters to UTF-8 if they fall into one of these scenarios:
+   *
+   * 1) when any of these characters:   ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞß
+   *    are followed by any of these:  ("group B")

+   * For example:   %ABREPRESENT%C9%BB. «REPRESENTÉ»
+   * The "«" (%AB) character will be converted, but the "É" followed by "»" (%C9%BB)
+   * is also a valid unicode character, and will be left unchanged.
+   *
+   * 2) when any of these: àáâãäåæçèéêëìíîï  are followed by TWO chars from group B,
+   * 3) when any of these: ðñòó  are followed by THREE chars from group B.
