// This file is used to Generate a new source Chajei Table File.
|

|
|
//
|
||
|
|
// it will read two files, one for Big5 and one for GB, to generate a new
|
||
|
|
// Chajei code table file.
|
||
|
|
//
|
||
|
|
// the two input files are sorted on the external keystroke pattern,(A1&A5)
|
||
|
|
// and both are complete Unicode files, ( there is 0xFEFF
|
||
|
|
// in its first two bytes),
|
||
|
|
//
|
||
|
|
// the two input files contain lots of lines,every line follows below format:
|
||
|
|
// XXXXXTCRL
|
||
|
|
// X: Key Code,
|
||
|
|
// T: Tab, 0x0009
|
||
|
|
// C: Unicode for this Character
|
||
|
|
// R: 0x000D
|
||
|
|
// L: 0x000A
|
||
|
|
//
|
||
|
|
// we will generate a new table source file, if the same pattern exists in both
|
||
|
|
// Big5 file and GB file, all those lines will be appended to the new file, and// the lines of Big5 will be written first, then GB Lines
