bson_utf8_escape_for_json - Man Page

char *
bson_utf8_escape_for_json (const char *utf8, ssize_t utf8_len);

• utf8: A UTF-8 encoded string.
• utf8_len: The length of utf8 in bytes or -1 if it is NULL terminated.

Allocates a new string matching utf8 except that special characters in JSON are escaped. The resulting string is also UTF-8 encoded.

Both " and \ characters will be backslash-escaped. If a NUL byte is found before utf8_len bytes, it is converted to "\u0000". Other non-ASCII characters in the input are preserved.

The two-byte sequence "C0 80" is also interpreted as an internal NUL, for historical reasons. This sequence is considered invalid according to RFC3629.

A newly allocated string that should be freed with bson_free() when utf8 is a valid UTF-8 string, or NULL if the (possibly invalid UTF-8) string could not be escaped.
