    No, this is an error. It is not the case that every glyph in the font
    must correspond to a single Unicode character. Some glyphs may very
    well be invoked by the font engine in order to render a sequence of
    Unicode characters -- modern fonts contain tables that indicate when
    this should be done.

    By the same token, a single character may have multiple glyphs to be
    used in different circumstances, again based on the font's tables.
