u suffix was here for a purpose. The patch has comment about multibyte characters. As 0x20u is unsigned, c was converted to unsigned char before comparison so multibyte characters were not considered control characters. Try enabling echo mode and typing non-ASCII characters (add some non-latin layout or use compose key or copy and paste '®').
