В	Copy Code
while( *sz2 ) { if( *sz2 != 'X' ) *sz1++ = *sz2++; else sz2++; }

The code copies the byte at sz2 to the location pointed to by sz1, then increments sz1 to receive the next byte. But if the next character in sz2 is a double-byte character, the assignment to sz1 copies only the first byte. The following code uses a portable function to copy the character safely and another to increment sz1 and sz2 correctly:

while( *sz2 ) { if( *sz2 != 'X' ) { _mbscpy_s( sz1, 1, sz2 ); sz1 = _mbsinc( sz1 ); sz2 = _mbsinc( sz2 ); } else sz2 = _mbsinc( sz2 ); }
