Unless it has changed recently, the first 64K code points of ISO-10646 are known as the Basic Multilingual Plane (BMP), which corresponds to ISO-10646. The other 'planes' are not currently used AFAIK, but they exist. Indeed, some code points from the BMP are reserved so Unicode can use multi-word encodings of the lower 4 planes. -- John (Max) Skaller, mailto:skaller@maxtal.com.au 10/1 Toxteth Rd Glebe NSW 2037 Australia voice: 61-2-9660-0850 checkout Vyper http://Vyper.sourceforge.net download Interscript http://Interscript.sourceforge.net
