The code you refer to is actually parsing a decimal value (like &) -
the hex case (like &) uses sscanf().

We ultimately pass val to Xapian::Unicode::nonascii_to_utf8() which
takes "unsigned" so there's not much point making val a wider type

While ISO C/C++ only guarantee that int is at least 16 bits, in
practice it is 32 bits on the platforms we support.
