Re: [NTG-context] mixed English and Arabic using Simplefonts?

2 Oct 2010

      Dear Wolfgang and Khaled,

Thank you both for your replies. This has been very helpful. May I ask one further newbie question of simplefonts: how do I change the font for just the "fallback" font, without affecting the mainfont? Is there a way to do this by setting the size in points, or in scale (percentage), or some other fashion?

In fontspec, i was accustomed to something like:

\newfontfamily{\arfont}[Script=Arabic,Scale=1.66,WordSpace=1.66]{Scheherazade-Regular}

I am sure there are equivalents for these feature (size, scale, wordspace); I've seen many features in the simplefonts pdf. But i'm unsure how to define something like "arfont" using simplefonts.

Many thanks,
Talal

\usemodule[simplefonts]

\setmainfontfallback[Scheherazade][range={arabic,arabicpresentationformsa,arabicpresentationformsb,arabicsupplement}]
\starttext
\input knuth
\textdir TRT ???? ???????!
\stoptext

My apologies if I'm dumbing down the level of discussion here. But I'm trying to get my head around fonts and bidirectionality using ConTeXt MkIV (as a rather unsophisticated user, not as a developer).
To begin with, since it's all bit much at once, I'm trying to use simplefonts. I am unclear how to establish English as my language and its font as my main font (using the default font), and Arabic as a secondary language (using Scheherazade).
What would I change in the ara-sty environment found on wiki.contextgarden.net/Arabic_and_Hebrew? Or, if I don't need to use this, should I define my own macro in my tex document for directionality?
I'm probably making a mess of some basic things here, but could use some help. I have working familiarity with Fontspec over on the XeLaTeX side of things, but the sparse documentation of simplefonts is leading to my uncertainty as how to proceed.
\usemodule[simplefonts]
%\setmainfont[Antykwa Poltawskiego]
\setmainfontfallback[Scheherazade][range={arabic,arabicpresentationformsa,arabicpresentationformsb,arabicsupplement}]
I think there is no need for presentation forms, they are deprecated
symbols not used for entering text.
