- ``\Uhhhhhhhh`` 32-bit Unicode character (hhhhhhhh is 8 digits)
The ``format`` argument is re-used as many times as necessary to convert all of the given arguments. If a format specifier is not appropriate for the given argument, an error is printed. For example, ``printf '%d' "102.234"`` produces an error, as "102.234" cannot be formatted as an integer.
The ``format`` argument is re-used as many times as necessary to convert all of the given arguments. If the given argument doesn't work for the given format, an error is printed. For example, ``printf '%d' "102.234"`` produces an error, as "102.234" cannot be formatted as an integer. printf will then also return non-zero.
It will also return non-zero if no argument at all was given, in which case it will print nothing.
