    Something IS definitively funny here.

    OK, here is my view of the gag.

    OS is Windows 2000 sp4, regularly AU-patched.
    CHARMAP.EXE is 5.0.2134.1, dated May 2001 (from SP2, carried upward).
    GetUNmame.dll is the matching equivalent.
    UNICODE.NLS (version-less) is dated May 2001, too.

    USP10.DLL (in case it influences indirectly) is 1.325.2195.6692 dated June
    2003 (plain SP4); I guess it does not influence in any way, since it does
    not appear in the process map...

    ArialUni.ttf is v.1.01, last modified 2002-11-18 16:23:15, 50377 glyphs.

    No problem to display Oriya letters...

    Not sure. With 2000, the glyphs in the PUA _are_ visible; those which are
    not are the glyphs without mapping, and the ones which mappings are in the
    "unknown" (to 2000) scripts (including Burmese, Khmer, Sinhala, in other
    words those in TUS 3+.) Oriya certainly is known to 2000.

    I do not know about XP here. However, since '05 2003sp1 also restricts
    itself to the same scripts (i.e., no way to display the Syriac characters
    from Estrangelo Edessa; now this DOES look like a bug, by the way), I guess
    all the NT 5.x should behave in very similar ways
    (LongHorn/Vista IS another beast, since at least I cannot launch LH's
    charmap.exe here!)

    Playing around a bit, I can say at least 2000's/2003's Charmap only shows
    the assigned codepoints (and only part of them, moreover, see above.)
