pango font for arrow keys

[Deepa Chacko Pillai <deepa chacko wipro com>]

Hi

I am porting GdkFont in stock-ticker to Pango. I am not able
to find the Pango font which will display the up/down arrow
characters. Previously, it was Symbol (Adobe).  When I used
Symbol as the font to Pango, it gave me "Invalid UTF8 string
passed to pango_layout_set_text()". What is the font I
should use to display such symbols like arrow.

Thanks
Deepa
