Hello,

I work on an Arabic font and have been a bit frustrating with the inability to copy-paste an Arabic (or Persian or other language) string into the Fontlab preview window.

I found this very useful applet: http://www.arabunic.free.fr/
This applet can convert an Arabic string into a unicode range (named \uXXXX) that can be pasted into the preview window of Fontlab and show the right contextual form. It also works with all other languages who have a special unicode for every isol-init-medi-fina form. (Arabic Presentaion Forms A and B).

I worked together with Stéphane Humbel to fix bugs on it, and add the possibility to use non-arabic languages with it.
There are still bugs we are going to fix (mainly lam-alef liga support and vocalization).

Still I think it can already be very useful to test Arabic fonts into Fontlab.

Please feel free to use it, test it, and send us feedback, suggestions or bugs.

Sylvain.

Merci beaucoup!
It would be more efficient without leading "u" and without leading zeros,
\u0020\u0627\uFEBC can be shortened to \20\627\FEBC
 
The length of the string in the FontLab preview window is always a problem, when you open a text file, a line can have only 1024 characters, when you paste, more text will fit.

So in sample texts it is far more efficient to use \E4 than /adieresis.

For the arabic texts: an extension to FontLab that can activate features in the preview window would be the proper solution, but we'll have to wait for FontLab 6.

thanks for the suggestions.
most of them have been incorporated in ArabUniC version 1.99h (online since a few days on the http://www.arabunic.free.fr) both leading characters and leading Zero issues have been fixed as options:
- fillable field (for leading characters)
- checkbox (to remove leading Zeros)

Thanks to Sylvain involvement (and patience), part of the ligature bugs have been fixed (lam-alef and some vocalization), but I beleive there are (at least) still some vocalization issues. They remain to fix.

He also provide a number of additionnal characters so ArabUniC extends from about 50 to nearly 200 the number of characters concerned.

many thanks to Sylvain and Luc(as)

regards
