It's a good example, and a good tool for Windows users w/o the strings
util (I say this because I now work within a Windows environment and I am
a bit shell shocked w/o all the tools I am familiar with). When I played
with it I only wanted/needed to pass the encoding in from the command
line, and not the pattern to search for. So here's a lil patch to try the
first param as the char encoding, and if it throws UnsupportedEncoding,
use this first param as a pattern instead. I also experienced
ArrayIndexOutOfBounds when setting the encoding to US-ASCII.
