I haven't tried grep-2.6.1 but read its changelog and seems they did major
UTF-8 improvements mainstream. With the new version, grep and fgrep are equally
fast if the pattern is actually a simple string without special characters.

I'm not fully satisfied with the result, though. With the old version "fgrep
-i" was extremely fast (around 0.1-0.2 seconds), with the new version "fgrep
-i" takes around 4-5 seconds. This should rather be addressed mainstream,
though...
