The error message is fairly obvious: parse_bom is only defined for char 
and wchar_t, not any other type.  (Looking at the implementation, I'm 
not convinced that it's correct for 32-bit wchar_t either, but that's a 
different issue, and could just be because I'm looking at an older 
version of Boost.)

Either file a bug report / feature request to get support added for 
this, or use one of the supported character types instead.

Don't forget to read the docs as well.  They suggest that there are 
known deficiencies and gotchas in the XML parsing/writing.
