    Well, I checked the 8859-2 mapping table, and the only contiguous ranges
    are of length 2, namely 0xA7-0xA8, 0xC1-0xC2, 0xCD-0xCE, 0xD3-0xD4,
    0xD6-0xD7, 0xDC-0xDD, 0xE1-0xE2, 0xF3-0xF4, 0xF6-0xF7, 0xFC-0xFD.
    All of these are places where Latin-1 and Latin-2 coincide.

    This is strongly true of Latin-1, -2, -3, -4: a character appears in the
    same codepoint or not at all. Unfortunately, Latin-3 is used only for
    Esperanto and Maltese, and Latin-4 is dead. The later Latins share only
    with Latin-1.
