[HarfBuzz] persian numerals

[Eduardo Castiñeyra]

Hi Ebrahim,

My problem is not how to change the numerals but when. For instance 
LibreOffice seems to be based on the context whereas MS Word detects the 
selected keyboard layout and takes that as the locale.

Given that I'm using the "hb_language_from_script"feature I was 
wondering whether it could deal with the locales as well.

But you are right. I was expecting not to have to solve this problem at 
all because it should be the input method the one that should deal with 
that. Now I realice if the input method fixed the problem, some 
softwares would not recognize ۲۳٫۴۵ as a number.

I will just set the locale of the script of the latest non-numeral 
character. I hope that works.

Thanks, and sorry for the off-topic!

Eduardo.
