`split': invalid byte sequence in UTF-8 (ArgumentError) #188
Description
Hi,
For a project, I'm storing diffs for each commit in forms of difffiles (diff per file) and patches, including the stats for each patch.
My script starts like -
require 'rubygems'
require 'logger'
require 'rugged'
require 'git'
# Include diff, difffile classes
load 'diff.rb'
load 'difffile.rb'
load 'helper.rb'
# Global array to store all the diffs
diffs_array = []
# Initialize both libraries
working_dir = `pwd`.chomp
rubygit_gem_repo = Git.open(working_dir, :log => Logger.new(STDOUT))
rugged_repo = Rugged::Repository.new(working_dir)
# Get all the commits for the project
commit_list = rubygit_gem_repo.log(nil)
# Get the initial empty tree state
empty_tree=`git hash-object -w -t tree /dev/null`
empty_state = rugged_repo.lookup("#{empty_tree.chomp}")
commit_list_array = commit_list.to_a
For 2 commits, I calculate the diff as follows:
diff_bw_commits = rubygit_gem_repo.diff(prev_sha, next_sha)
diff = Diff.new(prev_sha, next_sha, diff_bw_commits)
diff.generate_difffiles_and_stats
In the generate_difffiles_and_stats function, I'm doing the following:
@difffiles = []
# diff.class => Git::Diff
# Get the stats for the diff, before extracting individual difffiles
@stats = @diff.stats
diff = @diff.to_a
self.generate_stats
@num_difffiles = diff.size
@num_difffiles.times do |i|
difffile = DiffFile.new( diff[i] )
@difffiles << difffile
end
My script runs fine for simple commit histories that I created myself, but when I run it on project JSHint, I'm getting an error:

I researched about the error and found that the issue can be fixed by the answer in this StackOverflow answer.
Is it something that I am doing wrong?
Please let me know if you need any more information.
P.S. I know that this gem is not under active development, but it very nicely breaks down a Diff to Difffile to Patch. I can also easily access stats for each commit and stats per file. So, I stick to using it for diff purposes. I looked at the Rugged gem, but couldn't find such functionality. So, I just love this gem for this :)
