-/* Decode the next character, c, from buf, reporting errors in e.
- *
- * Since this is a branchless decoder, four bytes will be read from the

- * means the buffer _must_ have at least three bytes of zero padding
- * following the end of the data stream.
- *
- * Errors are reported in e, which will be non-zero if the parsed
- * character was somehow invalid: invalid byte sequence, non-canonical
- * encoding, or a surrogate half.
- *
- * The function returns a pointer to the next character. When an error
- * occurs, this pointer will be a guess that depends on the particular
- * error, but it will always advance at least one byte.

-  A dynamically growing memory buffer for trivially copyable/constructible types

-
-  +----------------+------------------------------+
-  | Type           | Definition                   |

-  | memory_buffer  | basic_memory_buffer<char>    |
-  +----------------+------------------------------+
-  | wmemory_buffer | basic_memory_buffer<wchar_t> |

-
-  **Example**::
-
-     fmt::memory_buffer out;
-     format_to(out, "The answer is {}.", 42);
-
-  This will append the following output to the ``out`` object:
-
-  .. code-block:: none
-
-     The answer is 42.
-
-  The output can be converted to an ``std::string`` with ``to_string(out)``.

+

+  **Example**::

+

+     fmt::memory_buffer out;

+     format_to(out, "The answer is {}.", 42);
