    The problem is the implication that ligature control belongs in plain
    text. By and large, for Latin it doesn't. For Latin, it doesn't make
    much sense to specify ligature formation involving certain characters
    in the absence of information on what font is being used. Some fonts,
    like Courier, will typically have no or very few ligatures. Other
    fonts, such as Zapfino, will have huge ligature repertoires.
