Arabic font marks problem

This topic was imported from the Typophile platform

hello there,

lately, I finished making an Arabic font with tashkeel (marks),
the result is nice in adobe programs (illustrator for ex), but while testing it in notepad or wordpad the problem appeared

when i add a mark to a letter it adds a useless space, like the image below

the image is captured from wordpad
I use win xp btw

I’m sorry I cannot help with your problem (and I don’t even read arabic), but I like your font! :-)

Thanks Riccardo :D

Mark glyphs need to be zero width and assigned OpenType "mark" glyph class, how to do that depends on the tools you use.

Thanks for replying Khaled,it works :)
marks were assigned to "mark" ,i edited the mark glyphs to be zero widths
