Fix #333 - do not remove non-breaking spaces

[u01jmg3]

Can you rebase against master, please? I'll fix Rector on my end.

Also, does this other space removal (line 646) affect your iCal feed?

Lines 642 to 647 in 6cbb1da

	if (!$this->disableCharacterReplacement) {
	$line = str_replace(array(
	' ',
	"\t",
	"\xc2\xa0", // Non-breaking space
	), ' ', $line);

This replacement of \xc2\xa0 into doesn't affect me. This would be & , right? The "non-breaking space" comes alone without HTML markup.

[u01jmg3]

It's the whole thing, both characters - I just wanted to check anyway.

What is \xc2\ xa0?
The \xc2\xa0 is the UTF-8 representation of the unicode U+00A0 (non-breaking space), which is shown as \xa0 in the representation of the decoded Unicode string.
