encoding of Italian man pages

Hi,
I have installed the Italian man pages of the shadow package on my system. =
The=20
character encoding of these manuals is UTF-8. My current locale is set as

LANG=3Dit_IT.UTF-8
LC_CTYPE=3D"it_IT.UTF-8"
LC_NUMERIC=3D"it_IT.UTF-8"
LC_TIME=3D"it_IT.UTF-8"
LC_COLLATE=3DPOSIX
LC_MONETARY=3D"it_IT.UTF-8"
LC_MESSAGES=3Den_GB.UTF-8
LC_PAPER=3D"it_IT.UTF-8"
LC_NAME=3D"it_IT.UTF-8"
LC_ADDRESS=3D"it_IT.UTF-8"
LC_TELEPHONE=3D"it_IT.UTF-8"
LC_MEASUREMENT=3D"it_IT.UTF-8"
LC_IDENTIFICATION=3D"it_IT.UTF-8"
LC_ALL=3D

Man expects to find the man pages by default in latin1 (ISO-8859-1) encondi=
ng.=20
=46rom the info page of troff:

*********************
Currently, the following input encodings are available.

cp1047
     This input encoding works only on EBCDIC platforms (and vice
     versa, the other input encodings don't work with EBCDIC); the file
     `cp1047.tmac' is by default loaded at start-up.

latin-1
     This is the default input encoding on non-EBCDIC platforms; the
     file `latin1.tmac' is loaded at start-up.

latin-2
     To use this encoding, either say `.mso latin2.tmac' at the very
     beginning of your document or use `-mlatin2' as a command line
     argument for `groff'.

latin-9 (latin-0)
     This encoding is intended (at least in Europe) to replace latin-1
     encoding.  The main difference to latin-1 is that latin-9 contains
     the Euro character.  To use this encoding, either say
     `.mso latin9.tmac' at the very beginning of your document or use
     `-mlatin9' as a command line argument for `groff'.
*********************

When using man,  groff converts the encoding of a man page to the current=20
locale. So there is a awful conversion (UTF-8 -> UTF-8) which messes up non=
=20
standard 7bit ASCII characters.

It would be great to have ISO-8859-1 default encoding for Italian man pages=
 to=20
avoid the problem described above.

Best regards,
