    Hello Pierre,

    ArialMT Italic and ArialMT BoldItalic have no glyphs for Arabic
    characters at all. It turns out to be a limitation of this font.
    Apart from this you hit a bug in XEP: since there are no glyphs used
    in the font being subset (e.g. in Arial-ItalicMT) our subsetting
    algorithm produces empty GLYF table for this font in the resulting
    document - that's the cause of the error message you see in the
    Acrobat. Thanks for drawing our attention for this problem.

    Best regards,

    PD> Hello,

    PD> I'm evaluating XEP at this time to use it in a Cocoon web application. I

    PD> a minimal fo sample and the associated screenshot.

    PD> As I open the generated PDF file with Acrobat reader, I got an error

    PD> Some characters won't be properly printed or displayed", and another one
    PD> "A substitute font can't be found" (messages translated from french by me).

    PD> To embed fonts, I uncomment the section relative to Arial font in
    PD> $XEP_HOME/etc/fonts.xml :
    PD> <font name="ArialMT"
    PD> ttf="C:\WINDOWS\Fonts\arial.ttf"
    PD> embed="true">
    PD> <alias name="Arial"/>
    PD> </font>
