Unofficial 2.056/2.058/Ruby 1.9.3 Windows 32bit data.csv:



data.csv, 2.056 -> 76351 msecs
data.csv, 2.058 ->  2573 msecs
data.csv, 1.9.3 ->  9170 msecs

Also I had to modify line 48 of the ruby file not knowing what 
I'm doing:

if text.force_encoding("UTF-8") =~ /#{rule}/u

Couldn't build it with ctRegex (Some Error, then ran out of 
memory).
