    No, slight correction: there was *speculation* as to what it might point
    to. But it isn't clear that it ever pointed to an *actual* currency.

    The rupee being used in different countries, it would be an exceedingly
    bad idea to modify the glyph.

    The character code doesn't encode the function, it encodes the graphic
    symbol. When that changes to a different graphic symbol, you need a new
    character.

    There's an archiving aspect to this that you seem to not be aware of. In
    the digital age, documents exist that contain just a font style and a
    plaint text character code. When these documents are reproduced years
    later, you do not want their appearance to be magically altered, just
    because a bad decision in the character coding community forced all
    fonts to be updated.

    In other words, if I used Times in 1991 to create a document with Rs,
    then I want to be able to load that in 2019 and show it with the old
    style for the Rs symbol, not whatever new symbol was invented, because,
    in 1991 that new symbol didn't exist.

    This is different from your favorite type of glyph correction: that
    case, where the standard inadvertently mixes font designs within a table
    of character codes, because sample fonts came from different sources. In
    such cases, the glyph change doesn't signify a different graphical
    symbol, but just tries to emphasize the fact that each font should use a
    *consistent* design across all its glyphs for that set of characters.

    For letters, and common punctuation, the typography is often settled
    enough that font vendors need little guidance from the Unicode code
    tables - for symbols the question of what are allowable/required
    variations is a lot less settled, so great care must be taken to not
    inadvertently raise questions or doubt about the identity of the
    character in question.
