ghostscript Some Russian letters disappear in PDF (bug 705476)

[Питерцев Эдуард Николаевич <cpan@telets.ru>]

    Hello.
    
    Please add a bug fix to ghostscript for debian 11 (ghostscript
    version 9.53.3~dfsg-7+deb11u2).
    Only 1 file needs to be corrected: devices/gxfcopy.c
    
    Ghostscript developers confirmed the error and changed the
    devices/gxfcopy.c file
    https://bugs.ghostscript.com/show_bug.cgi?id=705476
    
    I tried to download the source code from their website and compile
    and check Yes with the new gs error does not appear. Only the new gs
    does not have a cups device (-sDEVICE=cups),
    so it does not work with some printers.
    Please release the ghostscript 9.53.3~dfsg-7+deb11u2 update with
    this devices/gxfcopy.c file in mind
