BSON_APPEND_UTF8(3)		    libbson		   BSON_APPEND_UTF8(3)

SYNOPSIS
	  #define BSON_APPEND_UTF8(b, key, val)	\
	     bson_append_utf8 (b, key, (int) strlen (key), val,	(int) strlen (val))

	  bool
	  bson_append_utf8 (bson_t *bson,
			    const char *key,
			    int	key_length,
			    const char *value,
			    int	length);

PARAMETERS
        bson: A bson_t.

        key: An ASCII C string	containing the name of the field.

        key_length: The length	of key in bytes, or -1 to determine the	length
	 with strlen().

        value:	A UTF-8	encoded	string.

        length: The number of bytes in	value excluding	the trailing \0, or -1
	 to determine the length with strlen().

DESCRIPTION
       The  bson_append_utf8() function	shall append a UTF-8 encoded string to
       bson.

       value MUST be valid UTF-8.

       Some UTF-8 implementations allow	for \0	to  be	contained  within  the
       string  (excluding  the	termination  \0. This is allowed, but remember
       that it could cause issues with	communicating  with  external  systems
       that do not support it.

       It  is  suggested to use	modified UTF-8 which uses a 2 byte representa-
       tion for	embedded \0 within the string. This will allow these UTF-8 en-
       coded strings to	used with many libc functions.

       Due to legacy behavior, passing NULL for	value appends  a  null	value,
       not  a  UTF8  value.  To	 append	 a  null  value	directly, prefer using
       bson_append_null().

RETURNS
       Returns true if the operation was applied  successfully.	 The  function
       will fail if appending the value	grows bson larger than INT32_MAX.
