[XeTeX] No Unicode mapping available: GID=

[Joshua Grauman]

I get these errors from xdvipdfmx under Linux using the SIL Ezra font. 
Does this mean my utf-8 text has unicode characters that my font does not 
have? Is the GID the decimal value of the unicode character that is 
missing?

Thanks,

Josh
