Fabian Russell: > As far as I know, the first 32 [ code points ] (except CR and LF) > are just dead space. Is this correct ? No, US-ASCII is a subset of the set of Unicode code points. Unicode code points are 20 bits long, not 32. typedef wchar_t wchar ; typedef char32_t Uchar ; // UTF-16 requires a "Surrogate Pair" ( 2 wchars ) // to encode one 20 bit UTF-32 (Uchar) code point. Uchar _i32, i32 = U'⛏'; wchar pCh[2]; #define i32＞pCh( Ch, pCh ) hall( pCh[1] = 0, Ch >= 0x10000 ? *pCh = 0xd800 | Ch - 0x10000 >> 10, pCh[1] = 0xdc00 + ( Ch & 0x03FF ) : *pCh = Ch ) i32＞pCh( i32, pCh ); SurrogatePair = ( *pCh & 0xF800 ) == 0xD800 ; _i32 = !SurrogatePair ? *pCh : 0x10000 + ( *pCh - 0xD800 << 10 ) + pCh[1] - 0xDC00 ;
