/* Implementation note:
The printf format specifiers we use appear to be entirely standard,
except for the "long long" one, which is %I64 on Windows and %lld
everywhere else. We could use the C99 standard macro PRId64 for that,
but on at least one 64-bit-long GNU compiler, PRId64 is "ld", which is
considered to be incompatible with long long. So we have XMLRPC_PRId64.

&#x0d; is known in XML as a "character reference."

handle all valid UTF-8. Someday, we must do something more complex
