VALIDATING A UTF-8 SEQUENCE
To validate the string contained in my_string , use the following. You may pass -1 for the string length if you know the string is NULL-terminated.
if (!bson_utf8_validate (my_string, -1, false)) {
printf ("Validation failed.\n");
}
If my_string has NULL bytes within the string, you must provide the string length. Use the follwing format. Notice the true at the end indicationg \0 is allowed.
if (!bson_utf8_validate (my_string, my_string_len, true)) {
printf ("Validation failed.\n");
}
