# The current directory must contain the following files that can be found at
# http://www.unicode.org/Public/UNIDATA/:
# - UnicodeData.txt
# - Unihan_Readings.txt (you need to uncompress it from Unihan.zip)
# - NamesList.txt
# - Blocks.txt
#
# The generated file is named "kcharselect-data" and has to be put in kdelibs/kdeui/widgets/.
# Additionally a translation dummy named "kcharselect-translation.cpp" is generated and has
# to be placed in the same directory.
#
# FILE STRUCTURE
#
# The generated file is a binary file. The first 40 bytes are the header
# and contain the position of each part of the file. Each entry is uint32.
#
# pos   content
# 0     names strings begin
# 4     names offsets begin
# 8     details strings begin
# 12    details offsets begin
# 16    block strings begin
# 20    block offsets begin
# 24    section strings begin
# 28    section offsets begin
# 32    unihan strings begin
# 36    unihan offsets begin
#
# The string parts always contain all strings in a row, followed by a 0x00 byte.
# There is one exception: The data for seeAlso in details is only 2 bytes (as is always is _one_
# unicode character) and _not_ followed by a 0x00 byte.
#
# The offset parts contain entries with a fixed length. Unicode characters are always uint16 and offsets uint32.
# Offsets are positions in the data file.
#
# names_offsets:
# each entry 6 bytes
# 16bit: unicode
# 32bit: offset to name in names_strings
#
# names_strings:
# the first byte is the category (same values as QChar::Category),
# directly followed by the character name (terminated by 0x00)
#
# nameslist_offsets:
# char, alias, alias_count, note, note_count, approxEquiv, approxEquiv_coutn, equiv, equiv_count, seeAlso, seeAlso_count
# 16    32     8            32    8           32           8                  32     8            32       8
# => each entry 27 bytes
#
# blocks_offsets:
# each entry 4 bytes
# 16bit: start unicode
# 16bit: end unicode
# Note that there is no string offset.
#
# section_offsets:
# each entry 4 bytes
# 16bit: section offset
# 16bit: block offset
# Note that these offsets are _not_ positions in the data file but indexes.
# For example 0x0403 means the fourth section includes the third block.
#
# unihan_offsets:
# each entry 30 bytes
# 16bit: unicode
# 32bit: offset to unihan_strings for Definition
# 32bit: offset to unihan_strings for Cantonese
# 32bit: offset to unihan_strings for Mandarin
# 32bit: offset to unihan_strings for Tang
# 32bit: offset to unihan_strings for Korean
# 32bit: offset to unihan_strings for JapaneseKun
# 32bit: offset to unihan_strings for JapaneseOn
