If you want to output a single UCS4 character, use \code

os.put(c);

\endcode, not \code

os << c;

\endcode . The latter will not output the character, but the code point

|
as number. This is because we can't overload operator<< (our character
|
|
type is not a real type but a typedef). Narrow characters of type char
|
|
can be output as usual.
