[texworks] Override xunicode for one char?

[David Perry]

I need to print U+0060, the spacing grave accent ("the grave accent ` 
derives from . . . ").  I enter the character and it turns into a single 
left curly quote, which I think is done by xunicode.

Is there a way to override this for one character?  I have tried 
verbatim and \char"0060, both to no effect--the curly quote still appears.

Thanks - David
