    It is. It’s like typing "k" vs. "c" or "s" vs. "z" in some languages (if
    they’re homophones). Thw immediate problem is that there are still no
    cross-platform compatible input methods for scientific publishing that
    would go beyond a typical QWERTY keyboard layout. (All the "special"
    input methods are a bit insular). But given that you solve the problem
    of typing ZWJ and ZWNJ, the rest is a matter of editing the text. Just
    like you have to make sure in regular text that your quotation marks or
    dashes are right, in fraktur publishing, you need to make sure that your
    long vs. short "s"s are where they should be, and that the ligatures are
    where they should be.

    It’s an interesting case. First of all, saying "fraktur" is wrong
    because fraktur is only a subset of blackletter. In early 20th century,
    blackletter was considered a different writing system from "Antiqua"
    (Roman alphabet) for example in Germany. There was an opposition between
    the Roman alphabet and blackletter. When the Nazis abandoned
    blackletter, it was as if they switched to a different writing system.

    In OpenType, it is actually possible to share Unicode codepoints between
    different writing system. The languagesystem tagging mechanism allows to
    specify that a certain glyph represents the codepoint U+0041 in Latin
    script (script tag "latn") or it represents the codepoint U+0041 in
    Blackletter script (potentially, script tag e.g. "blak"). What do you
    think, John?
