Well, I get *different* errors, that at first sight appear
somewhat bizarre but don't give the impression of something
critical
bash$ groff -Kutf8 -pet -Tpdf RuTest.rof >RuTest.pdf
RuTest.rof: Too many glyphs used in font '39'
RuTest.rof: Too many glyphs used in font '39'
RuTest.rof: Too many glyphs used in font '39'
RuTest.rof: Too many glyphs used in font '39'
RuTest.rof: Too many glyphs used in font '39'
RuTest.rof: Too many glyphs used in font '39'
RuTest.rof: Too many glyphs used in font '39'
RuTest.rof: Too many glyphs used in font '39'
