[Groff] An uppercase mode

[Anton Shepelev]

Hello all,

I want to typeset headers in man pages (an-old.tmac)
differently for text-based and  PostScript  devices.
For  the  former  I want them to be uppercase, while
for the latter -- in the normal case, as  they  were
typed.

I  thought I would prepend the TH and SH macros with
code that would conditionally (.if n) enter an "all-
caps"  mode  and append them with corresponding code
to return back to  normal  mode;  or,  maybe,  write
wrappers  around  them so as to prevent any side ef-
fects, like translations'  affecting  various  traps
and  hooks.   But it turned out that simple requests
like

   .tr aAbBcC or
   .char aA

do not work with  Russian  (non-ACSII)  symbols  and
that I have to do:

   .char a\[u0431]

which  of  course only works with the PostScript de-
vice, but fails with latin1 which  I  use  for  text
output.

Will  I  have  to  switch to the UTF8 device instead
latin1 to achieve my goal, or is there a  device-in-
dependent way to implement the uppercase mode?
