Diff::LCS computes the difference between two Enumerable sequences using the
McIlroy-Hunt longest common subsequence (LCS) algorithm. It includes utilities
to create a simple HTML diff output format and a standard diff-like tool.

This is release 1.2.2, fixing a bug that prevented comparison of values that
are not US-ASCII-compatible. Thanks to Jon Rowe for finding and providing most
of the work behind this issue. This is a recommended release.

Changes:

## 1.2.2 / 2013-03-30

* Bugs Fixed:
  * Diff::LCS::Hunk could not properly generate a difference for comparison
    sets that are not US-ASCII-compatible because of the use of literal regular
    expressions and strings. Jon Rowe (JonRowe) found this in
    rspec/rspec-expectations#219 and provided a first pass implementation in
    diff-lcs#15. I've reworked it because of test failures in Rubinius when
    running in Ruby 1.9 mode. This coerces the added values to the encoding of
    the old dataset (as determined by the first piece of the old dataset).
