[XeTeX] XeLaTeX not using language-specific glyphs with Scheherazade 2.x

[Lammert, Richard]

(Sorry about that empty message with one attachment--clicked the wrong
button.)

The following example attempts to use language-specific glyphs from
Scheherazade, but does not work with Scheherazade 2.0 or 2.01. The example
*does* work with Scheherazade 1.005 (see attachments arabic-test-1.005.pdf
and arabic-test-2.01.pdf)

However, when I use TypeTuner to produce language-specific fonts for each
of the three languages (last three lines of each test file), XeLaTeX
properly shows the correct contextual forms. Since XeLaTeX reads the glyphs
properly from the tuned fonts, it appears to me that the language
information is not being interpreted properly in the base font. I am using
XeLaTeX 0.9999.3, fontspec v. 2.3c, and bidi v14 on an iMac.

Minimal working example follows:

%!TEX TS-program = xelatex
%!TEX encoding = UTF-8 Unicode

\documentclass{memoir}
\chapterstyle{bianchi}

\usepackage[no-math]{fontspec}
\usepackage{bidi}

\newfontfamily\arabic[Renderer=Graphite,Script=Arabic]{Scheherazade}
\newfontfamily\kurdish[Renderer=Graphite,Script=Arabic,Language=Kurdish]{Scheherazade}
\newfontfamily\sindhi[Renderer=Graphite,Script=Arabic,Language=Sindhi]{Scheherazade}
\newfontfamily\urdu[Renderer=Graphite,Script=Arabic,Language=Urdu]{Scheherazade}
\newfontfamily\kurdishsel[Renderer=Graphite,Script=Arabic]{Scheherazade
LngKur}
\newfontfamily\sindhisel[Renderer=Graphite,Script=Arabic]{Scheherazade
LngSin}
\newfontfamily\urdusel[Renderer=Graphite,Script=Arabic]{Scheherazade LngUrd}
\newcommand{\arabicfnt}{\arabic\fontsize{22}{26pt}\selectfont}
\newcommand{\kurdishfnt}{\kurdish\fontsize{22}{26pt}\selectfont}
\newcommand{\sindhifnt}{\sindhi\fontsize{22}{26pt}\selectfont}
\newcommand{\urdufnt}{\urdu\fontsize{22}{26pt}\selectfont}
\newcommand{\kurdishselfnt}{\kurdishsel\fontsize{22}{26pt}\selectfont}
\newcommand{\sindhiselfnt}{\sindhisel\fontsize{22}{26pt}\selectfont}
\newcommand{\urduselfnt}{\urdusel\fontsize{22}{26pt}\selectfont}

\newcommand\arabtext{م ممم - ه ههه  -   ◌ٍّ   ◌ِّ   }

\begin{document}

default: \par \RL{\arabicfnt\arabtext}

Kurdish: \par \RL{\kurdishfnt\arabtext}

Sindhi: \par \RL{\sindhifnt\arabtext}

Urdu: \par \RL{\urdufnt\arabtext}

Languages implemented with TypeTuner:

Kurdish: \par \RL{\kurdishselfnt\arabtext}

Sindhi: \par \RL{\sindhiselfnt\arabtext}

Urdu: \par \RL{\urduselfnt\arabtext}

\end{document}
