Drop down in local Gujarati fonts
 

I have a data sheet where all the data was typed in a local language
Gujarati font. When we look at the cell, it shows the data in gujarati
but if you look at the formula bar, it shows english cherecters which
looks like junk. Now I want to use auto filter. In auto filter also it
shows english cherecters which looks like junk.

Is it possible to show data in gujarati fonts in autofilter drop down?
If possible, it will greatly increase the efficiency. Pl note that the
change must be limited to this workbook coz other workbooks uses
english only.
