I've got an example which is meant to show the problem (, but 
unfortunately I can't make it generate the error which others are seeing. is a utf-8 file and I have used -k in a utf-8 user account 
(LC_CTYPE=en_GB.UTF-8) and with -Kutf8 in an old style account 
(LC_CTYPE=en_GB), neither produced an error from grep.

This leads me to suspect there is something in my version of grep which 
"understands" that UTF-8 files are not binary data. I believe compiling grep 
with NLS support is optional, so may be people who get this error are using a 
grep without language support.

One possible solution would be to replace the greps with a perl regexp, but I 
also have no objection to LC_ALL=C, if this fixes it. Be careful it only 
applies to the greps not anything else.
