Re: TrueType/OpenType rendering bug in PIL 1.1.7?

I ran you code on my machine (win 7 Python 2.6.4, PIL 1.1.6) and after
changing the font names (they are different on my system) I got
similar problems, but not the same. I did notice that your image has
"fish & fhips" whereas mine says "fish & chips" Something seems to be
slightly off.
Hope that helps.
