Hi, I am having trouble using Text::Levenshtein. Here's an example:

use Text::Levenshtein qw(fastdistance distance);

print fastdistance("history","hustory"), "\n";
 # prints "2"
[download]

IMHO, this should print "1" because there is only one substitution necessary to get from "history" to "hustory", but instead it returns "2". Interestingly enough, this works as expected:

print fastdistance("gistory","history"), "\n";
 # prints "1"
[download]

Any idea what I am doing wrong? Or do I have the wrong notion about how Levenshtein distance actually works?? I also tried using distance, but then something seriously goes wrong:

print distance("gistory","history"), "\n";
 # prints "1234561234561"
[download]

I am using ActivePerl on Windows 7. The input file is ANSI. I am thankful for all hints!

Cheers and thanks, Christian
