I cannot use UTF8 signs, like " ' " or €, but get a ? instead.

Your pull request is a good job.

I will improve it with testing if the text is Unicode : http://stackoverflow.com/questions/4407854/how-to-detect-if-have-to-apply-utf8-decode-or-encode-on-a-string .

Hi, Progi1984,
please, consider the issue #34 and its PR #37. It contains everything necessary for Unicode detection.

The same fix is already merged into PHPOffice by Mark Baker.
