error with lualatex but not with xelatex

[Zdenek Wagner]

Hi Ken,

I do not know which languages you want to cover but you will
definitely have to increase \baselineskip for Indic scripts derived
from Brahmi (Devanagari, Gurmukhi, Gujarati, Bengali, ...) and even
more for Urdu where nastaaleeq is the basic style. You can see a part
of my book at http://icebearsoft.euweb.cz/bharat.php which is written
in Czech with names given also in Hindi and sometimes in Urdu. Watch
especially the last two lines of the table of contents (Obsah). The
Urdu text can be even higher than shown there.
