    But that specific use is the same as the use of the reversed t, h
    ligature that the i.t.a. uses and the proposed U+0246 (LATIN
    SMALL LIGATURE ITALIC TH) from N2656. While all three
    have different glyphs, they all represent a voiced th in English,
    and it is extremely unlikely that any document would use more
    than one such form. The distinction between the glyphs would
    seem to me to be more appropriately encoded by font than by

    Even if one admits that there is sufficient distinction between
    the i.t.a. voiced th and the other two glyphs to merit a distinct
    code point for the i.t.a. character, (an admission that further
    reflection convinces me is not unwarranted) the same
    cannot be said for LATIN SMALL LETTER TH WITH
    STRIKETHROUGH and the proposed LATIN SMALL
    LIGATURE ITALIC TH of N2656. Both are the result of a
    particular dictionary's attempt to distinguish between unvoiced
    and voiced th in a manner that is readable as plain text if the
    font variation (strikethrough or italic ligature) is ignored.

    Furthermore, in yet another dictionary (Webster's New
    Twentieth Century Dictionary, Unabridged, 2nd ed.[World
    Publishing Company,1962]) A plain th ligature with the
    connection formed by the extension of the horizontal bar
    of the t is used to represent the voiced th sound. Making
    a consistent font distinction within a dictionary to indicate
    the voiced th is part of American English lexicography,
    but the distinction used is not consistent between
    dictionaries. As such I feel that encoding one character
    for the lexicographic voiced th and using a choice of
    font to determine the exact glyph would be preferable
    to encoding separate codepoints for what is in my
    opinion the same character.
