Even if abandon the issue of coding arbitrary characters to typeset
verbatim, - no. As of `tetex-latex-3.0-4'
`fancyvrb' v2.6, with DG/SPQR fixes <1998/07/17> (tvz)
breaks `\index' commands easily. `\index{WORD!WORD}' works,
`\index{WORD!WORD-W}' do not. Again, may even write to the package
maintainer.
