Here in my code, i just mention 3 different UTF-8 strings as labels on 3
diffrerent buttons, and i am not mentioning any font related info here.
But still the pango is able to render proper language fonts. I went in
fonts-cache-1 file & tried to swapp the font files in terms of their order.
But still it's abl;e to render exact language fonts, so i want know how
exactly ht epango is able to map excat .ttf files for a given UTF-8 string.
Using this in my application i want take control of font changing & style &
size changes across multiple ttf files.

Here i have attached 2 simple code examples for ur reference.
PLs guide me for further. I donno if at all i can send attachments in mail
lists, or do i have to paste in the mail body itself? Pardon me if i have
done the wrong thing..
