+`[ostream.formatted.print]/3 <http://eel.is/c++draft/ostream.formatted.print#3>`_ A terminal capable of displaying Unicode
+--------------------------------------------------------------------------------------------------------------------------
+
+The Standard specifies that the manner in which a stream is determined to refer
+to a terminal capable of displaying Unicode is implementation-defined. This is
+used for ``std::print`` and similar functions taking an ``ostream&`` argument.
+
+Libc++ determines that a stream is Unicode-capable terminal by:
+
+* First it determines whether the stream's ``rdbuf()`` has an underlying
+ ``FILE*``. This is ``true`` in the following cases:
+
+ * The stream is ``std::cout``, ``std::cerr``, or ``std::clog``.
+
+ * A ``std::basic_filebuf<CharT, Traits>`` derived from ``std::filebuf``.
+
+* The way to determine whether this ``FILE*`` refers to a terminal capable of
+ displaying Unicode is the same as specified for `void vprint_unicode(FILE*
+ stream, string_view fmt, format_args args);
+ <http://eel.is/c++draft/print.fun#7>`_. This function is used for other
+ ``std::print`` overloads that don't take an ``ostream&`` argument.
+
