>Description:
$ egrep -V
egrep (BSD grep) 2.5.1-FreeBSD

$ echo abc > testfile
$ iconv -f ASCII -t UTF-16LE testfile > utftestfile

$ egrep -c "a.b" /tmp/utftestfile
1
$ egrep -c "a.b|d" /tmp/utftestfile
0


The expected result is that the second "egrep" command should also return 1. This works as expected when using GNU grep 2.15 installed from ports. Also this works as expected with "bsdgrep -E" on FreeBSD 9.1 i386 system.
