    This library is not a class. Use the `GXUNC <geosoft.gxapi.GXUNC>` library functions
    to work with Unicode characters and strings. Since version 6.2
    all strings are represented internally in the the GX engine
    as UTF-8. The character set concept was discarded as a way to
    work with characters that does not fall within the normal
    ASCII range 0x01-0x7F. The utilities here aids with any new
    functionality that is now possible (e.g. an expanded symbol range
    with TrueType fonts).
