LaTeX export of a file with some accented characters

[Vikas Rawal]

I have an org file with some names (not all) that have accented characters. But 
when I try to export, I get errors such as this:

Sāṅkr - 65190: word not found

What do I do to make Org export these correctly? Is there a way to make Org 
export even if it does not recognise the characters?
