Subject Re: FOP-ComplexScript (connectivity, direction and fonts of Arabic)

Thanks for the further update. In general, you should not be using font
metric files with FOP 1.0 or later.

Regarding Arial, Times New Roman, and Courier New fonts, I have not
explicitly tested these for Arabic support, but I will look into it. Keep in
mind that the Complex Script support requires OpenType fonts to support
GDEF, GSUB, and GPOS to perform contextual substitution and mark (e.g.,
vowel sign) placement. So if the fonts you used do not have these tables,
then FOP CS will not produce the desired results.

The fonts for which I have tested FOP CS are listed at
http://skynav.trac.cvsdude.com/fop/wiki/SupportedFonts.

Regarding the problem you report with Scheherazade and Lateef, I'm aware of
this, and a ticket is already filed for it at
http://skynav.trac.cvsdude.com/fop/ticket/38.

Regards,
Glenn
