Nothing special, I always expect interline space to be fixed, I don't know if TeX always make interline spacing variable, but this wasn't an issue with English text. However, with Arabic, Tashkil marks seems to always cause a noticeable extra whitespace above the line. See the uneven distribution of vertical whitespace in this example (it can be even worse than this in reality):
for arabic you really need to set the interline space (idris might have more input on this)
- it has more height than depth
Not always عٍ or فيٍ is as deep as high is أً.
so for say 12pt arabic we should use 8pt ht and 8pt depth?
I'm not sure about this, but I'd rather trust the font designer for knowing better about his font, and something like in the attached file (except it doesn't work :) see my other mail)
it's a gray area ... if we obey the ht/dp spec of a font (ascender and descender) we end up with an unpredictable mess (actually comparable to setting the baselineskip to 0pt and trusting the ht/dp of glyphs to force the right line spacing) in dtp there's aways this rather strict grid Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
