 * 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.
