Hello,

I observe the following error message after exiting the pager (less) for
"man grep":

> man: command exited with status 127: iconv -c -f UTF-8 -t CP1251//TRANSLI=
T | col -b -p -x | sed -e '/^[[:space:]]*$/{ N; /^[[:space:]]*\n[[:space:]]=
*$/D; }'

The easiest way to reproduce this is to run

> man grep >/dev/null

in a ru_RU.CP1251 environment:

> $ locale
> LANG=3Dru_RU.CP1251
> LC_CTYPE=3D"ru_RU.CP1251"
> LC_NUMERIC=3D"ru_RU.CP1251"
> LC_TIME=3D"ru_RU.CP1251"
> LC_COLLATE=3D"ru_RU.CP1251"
> LC_MONETARY=3D"ru_RU.CP1251"
> LC_MESSAGES=3D"C"
> LC_ALL=3D

The same for en_US locale:

> man: command exited with status 127: iconv -c -f UTF-8 -t ISO-8859-1//TRA=
NSLIT | col -b -p -x | sed -e '/^[[:space:]]*$/{ N; /^[[:space:]]*\n[[:spac=
e:]]*$/D; }'

The issue is not reproducible in UTF-8 locales.

grep(1) seems to be the only manual page affected.


Regards,
Andrey.
