Similar care should be take to ensure the data is in the correct format
when calling ASN1_STRING_set().
+=head1 RETURN VALUES
+
+ASN1_STRING_length() returns the length of the content of B<x>.
+
+ASN1_STRING_get0_data() and ASN1_STRING_data() return an internal pointer to
+the data of B<x>.
+
+ASN1_STRING_dup() returns a valid B<ASN1_STRING> structure or B<NULL> if an
+error occurred.
+
+ASN1_STRING_cmp() returns an integer greater than, equal to, or less than 0,
+according to whether B<a> is greater than, equal to, or less than B<b>.
+
+ASN1_STRING_set() returns 1 on success or 0 on error.
+
+ASN1_STRING_type() returns the type of B<x>.
+
+ASN1_STRING_to_UTF8() returns the number of bytes in output string B<out> or a
+negative value if an error occurred.
