Add a failing test about titles using non-Latin scripts

[javiereguiluz]

Title says it all. The problem is in this line:

https://github.com/doctrine/rst-parser/blob/35c61ece3a209a742f9382a4b4f5680365979750/lib/Environment.php#L492

Should I create a PR in Doctrine RST parser to add Symfony String as a dependency and slugify strings with it?

[OskarStark]

is the underline to long, or is it just because of the non latin chars?

[javiereguiluz]

Yes, it's not the same. The title is 9-char long, so I updated the --- to be 9-char long too. It looks very ugly now ... but in theory is fully correct now. Thanks!
