No, the other was wrong too, poppler has a very weird indenting pattern and is difficult to get right, it's basically 2 spaces for each indentation but when you have 8 spaces it gets replaced with a tab character > > >> I implemented a patch which supports CJK fonts in the postscript output > >> device and on Windows platforms in general.
