The UCS2 is considered obsolete! Nothing else needs to be said. :) > Have a look at the full Unicode codepages, what is and what is not > part of the BMP. Download the Unicode eBook chapters and look at the section "Details of Allocation" normally in Chapter 2. There are lots of useful things in Plane 1-16 (BMP being Plane 0). Like I said, outside the BMP, less is used for the spoken languages, but there are some CJK characters in Plane 2. Plane 1 has many interesting things for "modern applications" like Domino Tiles, Advanced Math symbols (which we use in our company), Map Symbols often seen on GPS units, Mahjong Tiles, Musical symbols, Smiley Face symbols used in emails and IM programs, System of Divination symbols, Large Historic Script area, Large private areas (any apps that ship custom fonts could use those private areas - MacOSX uses the private areas for the "apple" symbol in their fonts) and many more. The reluctance to support Planes 1-16 is often seen by UTF-16 or UCS-2 users, because they are just lazy! That is just wrong. I'll say it again, that is what makes UTF-8 so great. NO special handling or implementation is required to handle the _whole_ Unicode character set. Implement UTF-8 to handle the BMP (Plane 0), and you get handling for Plane 1-16 for free. -- Regards, - Graeme - _______________________________________________ fpGUI - a cross-platform Free Pascal GUI toolkit http://fpgui.sourceforge.net _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
