hmm reinstall from github,
- i added an option to set input encoding (its just passed on to
readLines(), see the help of that base function)
- if you see weird character strings like
\033[33mreturn\033[39m, thats not encoding related. Those are for the colour print output with the package crayon.
as.data.frame() should now automatically removes this color information, but its pretty slow.
The package should probably be rewritten to save the match indices for each row, instead of the color-formatted string, but I was going for quick and dirty when I wrote it. I wont be able to put any work into the package soon.. sorry... 
Put on the plus side the package is really simple. You should be able to modify it yourself if you need some special functionality
