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 representation for  embedded  \0
       within  the  string.  This  will  allow these UTF-8 encoded 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.
