Routine Description:

    Retreive a unicode value corresponsing to a particular desired linedraw
    character. The FarEast font we use during Setup does not have these chars
    so they are actually hand-placed into the in-memory image of the font
    and we assign fake values that work during setup.

Arguments:

    WhichChar - indicates which line draw character's unicode value
        is desired.

Return Value:

    Unicode value for desired line draw character.
