Problem with combining characters

[lostfocus]

When trying to debug #274 I ran into a weird-ish problem. I got a string from a source that looked like a "normal" unicode string with two German umlauts, but it turned out to use Combining Characters (This StackOverflow question sent me down the right path in the end: Strange umlaut encoding on file system)

I'm not too sure if it's within the scope of this library to handle these kinds of characters, but I thought I'd put this information here anyway, in case someone else has the problem.

If you have the intl extension installed on your system you can use the Normalizer class to fix that issue:

$this->slugify->slugify(
	\Normalizer::normalize(
		"Erla\xCC\x88uterungsbroschu\xCC\x88re"
	)
);

@lostfocus Interesting. I think it should be possible to add the German umlauts with combining characters to the ruleset and it should work. But I have not tried that out.
