	// Simplist method is to use a user-defined ESCAPE char to shift
	// into color mode, or mouse text mode.  The other solution
	// is to use a wide-char, simulating unicode16.
	//
	//    C1C0 char16 of High Byte (c1) and Low Byte (c0)
	// 1) --??  Con: Colors chars take up extra chars.
	//          Con: String Length is complicated.
	//          Pro: simple to parse
	//
	// <-- WE USE THIS
	// 2) ccea  Pro: Efficient packing of plain text and mouse text
	//          Pro: Color is optional (only record new color)
	//          Con: need to provide char8 and char16 API 
	//          Con: little more difficult to parse/convert plain text
	//          i.e.
	//       ea = 0x20 - 0x7F ASCII
	//            0x80 - 0xFF Mouse Text  '@'-'Z' -> 0x00 - 0x1F
	//    cc    = ASCII '0' - '9' (color)
	// 3) ??cc  Con: Colors chars take up extra chars
	// 4)  f??  Con: Colors chars take up extra chars
	//
	// Legend:
	//       f Flag
