phpspec/php-diff does not work correctly with utf-8

[morivitalii]

for example, if a line has some russian vowels ("a", "о", "и", and and etc), then the $ diff->render($ renderer) returns an empty string. Can you adapt phpspec/php-diff to work with utf-8?

I can't reproduce it. Can you provide an example code?

[morivitalii]

very strange behavior. for example
$renderer = new DiffRendererHtmlInline;
$diff = new \Diff(['оку'], ['оока']); or $diff = new \Diff(['око'], ['ока']);
return empty string. but $diff = new \Diff(['оку'], ['ока']); all ok. I do not know what the problem
I tested on PHP 5.4.22 and PHP 5.5.6. the same result.

Reproduced. I don't think it will be solved in any of sources we're using. Need to think about it...

Since it's not critical I've set milestone to 2.1. If you have an idea how to fix it or want to try implementing diff properly let us know. Thanks!

@yoopy have/can you tested/test it with this (not merged) pull request for php-diff: phpspec/php-diff#5 ?

[samdark]

We can consider switching to https://github.com/yetanotherape/diff-match-patch

phpspec/php-diff#5 is merged now and contained in release 1.1.0. can we close this?
