No. That would result in "there is no character <XX> in font <YY>"  
messages in the .log file when you run xetex (provided  
\tracinglostchars is positive). They'll also show in the terminal if  
\tracingonline is positive.

No, it's the glyph ID in the truetype font (a purely internal number).

These messages mean that your output includes some glyphs for which  
xdvipdfmx was not able to determine a corresponding Unicode character  
for the CMap resource in the PDF file. Therefore, although it should  
still look fine, these characters may be missing if you try to copy- 
and-paste text from the PDF.

As this is a pretty hit-and-miss affair anyhow, except with the  
simplest fonts/scripts/PDFs, it's best to regard PDF as a view-and- 
print medium, not a text interchange format.
