INPUT problem in new language pack

[ysulaiman]

I'm very sorry that I don't know this is the right place or not to send my post here,because I didn't speak Farsi,but my language using some Farsi letters.So I need your help.
I'm trying to creat a Uyghur language pack of Joomla 1.5.7 and translating some files of site language pack with install translation manager.
The Uyghurs is a Turkic-speaking ethnic group ,with a population about ten millions and inhabiting in the area of Central Asia and west part of China.The official writing system of Uyghurs is Arabic-Script Uyghur,made up 8 vowels and 24constants,either borrowed or adapted from Arabic and Farsi alphabets.The problem is no Unicode Uyghur standars until now .
We solved the problems of DISPLAY of Uyghur letters in web pages using Microsoft WEFT(Web Embedding Fonts Tool) to make a eot file,and also solved INPUT Uyghur fonts to web pages directly using the following js file before:

Now,I'd like to ask,if we finished translating language packs to Uyghur,how to add the js files to system files and where (like template or themes)so that we can INPUT Uyghur fonts directly in the editor pages as well as other pages?
Thank you.
