Re: [NTG-context] arab (omega)

Dear gang, I have redone this. Now there are two filter sequences, one for main text and one for using the arabic-font digits in math mode. http://wiki.contextgarden.net/Aleph_Guide#Installing has been updated, get the new uni2cuni.zip. I'll update m-gamma soon so this will be part of the distro if Hans accepts-) Here is a test file that works here. Note (see the sqrt example) that omarb apparently does not have U+066B, the Arabic decimal point. And the Arabic comma maps to the lm comma in math mode (since omarb maps the arabic comma to U+002C in the omarb virtual font-sigh). So there is further work needed to get this all just right, including recompiling the fonts etc...

My guess is you could just remove the punctuation support from the current OTP. If a user really needs to say "1.2 million", (s)he can just write $1.2$ instead, which is more or less standard TeX practice anyway.

It is my understanding that the contents of $$ is unaffected by OTPs (and if it is not, it should be made so. Math is a language on its own).

ok, it's done. The new ocp is here: http://wiki.contextgarden.net/images/2/27/Uni2cuni.zip

and the instructions are here:

http://wiki.contextgarden.net/Aleph_Guide#Installing

Now, in normal text, +, -, and . are treated as separators, not plus sign, minus, and decimal point. If you want math use $$ etc. but then you will get the math font not omarb (which is standard practice in the Arabic-script world).

I have no idea if this affects Hans' solution (have not upgraded yet); this is all experimental so things may change.

An aside: Classical Arabic is more sensical. Consider the number 3721. In classical Arabic one says, "one and twenty and and seven hundred and three thousand", which makes much more sense for a r-l language. So one would write the numeral from r to l and it would look the same. How decimals would be handled in the classical case needs a bit of research
