As well as using @tex instead of @macro as Jacob said, where are you
getting the names \rua, \rube, \ruve from?

You would also have to make sure a Cyrillic font was loaded and access
the glyphs in that font. Look at the definition of \euro in
texinfo.tex for how a font can be loaded on demand.

I don't foresee a problem with adding this to texinfo.tex as it would
probably be only slightly more complicated than the Greek alphabet.

I expect that the document I sent earlier was written in the KOI-8
encoding (an 8-bit encoding) rather than Unicode.

I'm curious what the use of this is: do you speak Russian? Do Russian
mathematicians use Cyrillic letters for variables?
