Desktop/Whiteboards/Basecode

Some features of the proposed Basecode:

• base on BMP of Unicode with code range from 0000 to FFFF

• BTF-8 as default encoding with same rules for UTF-8

• remove most of CJK ideographs and other composable characters

• keep and supplement radicals for composable characters

• move not composable characters outside BMP back into BMP

Hard works will be in font-related libraries:

• by means of Ideographic Description characters (2FF0~2FFF) to represent composable characters

• include libdgg (Library of dynamic glyph generator) into freetype to draw composable characters
