------- Additional Comments from Holger Freyther <zecke at selfish.org>
Only ' ', '\t' has the benefit of being fast with QFontMetrics::width. Any
other charachter might or might not have different rounding and about the same
speed as harfbuzz. This is a significant improvement on the pageloading test.
