    What I wanted to convey is that these abbreviations cannot be
    globally applied to a text, as they are governed by morphological
    issues (possibly also by typographical considerations, or may be
    just arbitrary, as Ken had suggested). So, they should be somehow
    coded in the text, whenever the user wants to preserve them, akin
    to the notorious "Wachstube" vs. "Wachſtube" example. A glyph-
    substitution automatism is not apt for this sort of happening.

    On the contrary, I think this is a text feature and not a mere rendering
    issue. Hence, I see two possible solutions:
    - mark the abbreviation with a particular character (or character sequence),
       e. g., U+006D U+0304 (abbr.) vs. U+006D U+006D (plain), or
    - mark the plain (unabbreviated) occurence of the characters,
       e. g., U+006D U+U+200B U+006D (plain) vs. U+006D U+006D (abbr.).

    I'd prefer the former one, because it marks the deviation from the
    prevalent usage.

    Best wishes,
