I don't know. Simple answer is you need to find a printer-driver/terminal
that performs the correct translation. At this level you've a redhat
problem.

At compiler level, you'll have to run it by comp.lang.c. Even though
compilers have accepted \v for years it was based upon implementation, luck
and common sense: in my previous post I knew that printer was sat waiting
for ascii characters so I can redirect output to directly, unfiltered.

In or around c99 I believe \v (and I think \a) were formally adopted. \v may
have different or little meaning in some languages so there's a stronger
notion of internal compiler representation (where \v exists) against
external representation (what \v turns into when written to a file) in much
the same manner as \n translates differently across win32/unix/mac etc.
