    And, in this case you are wrong as well ;-)

    There is no mapping of the glyph to 004A in the font's CMAP table. The
    fact that the smiley glyph is displayed for "J" is a Windows thing,
    whereby it adds an extra mapping layer from F020..F0FF in the font to
    ASCII codepoints if the font has a symbol encoding. This is no doubt
    for compatibility with pre-Unicode symbol fonts that did use ASCII
    mappings, but nevertheless the font itself does not have these ASCII
    mappings, only the Unicode ones.
