First of all, thanks for the hint, the path in the plugin directory was wrong, I just corrected it.
Then secondly, there should not be a problem with the text in test objects, did you use the wkhtmltopdf package from your package manager or from the wkhtmltopdf website?
If you only run wkhtmltopdf on your console, what does the "Name" in the head say?
Name:
wkhtmltopdf 0.12.5 (with patched qt)
It should read like the above.
