    Fact is that a text written in pre-3.0-Unicode which contains U+03D5
    is no longer displayed correctly with current Unicode encoding and
    fonts. For mathematics, it can really be confusing. How can VS
    combinations help here?

    I always thought such a szenario is against the Unicode idea. In this
    particular case, designing a different shape to U+03D5 changes the
    meaning of that character since in older Unicode versions the
    explanatory text doesn't describe which of the two characters is the
    curly version and which is the stroked one, thus implementors had to
    fall back onto the used glyphs in the Unicode book.

    Note that I don't say that it was a bad decision of the UTC to clean
    up the situation. I only say that the found solution isn't backwards
