%% CHARACTER SET: ASCII only
%%
%% No 8-bit characters are defined in this file. BibTeX will not accept
%% characters with a value >= 128.
%%
%% SORTING ORDER: English
%%
%% BibTeX's standard sorting order is based simply on the codepage
%% value of each character, resulting in an alphabetical sorting
%% order of A..Za..z. We want a "normal" English sorting order of
%% Aa..Zz.
%%
%% WARNING
%%
%% This is a BibTeX Codepage and Sort definition file (CSF). It is
%% used to define the 8-bit character set used by BibTeX and the
%% order in which those characters should be sorted. The file
%% format is documented below this header section.
%%
%% This file will only work with the 8-bit implementation of BibTeX
%% written by Niel Kempson and Alejandro Aguilar-Sierra. It is
%% available by anonymous FTP from these Comprehensive TeX Archive
%% Network (CTAN) sites:
%%
%% ftp.tex.ac.uk:/tex-archive/biblio/bibtex/8-bit

%% FILE FORMAT
%%
%% The codepage and sorting order (CS) file defines how BibTeX will treat an
%% 8-bit character set, specifically which characters are to be treated as
%% letters, the upper/lower case relationships between characters, and the
%% sorting order of characters.
%%
%% The CS file may contain a number of sections, each presented in the
%% form of a TeX macro:
%%
%% \section-name{
%% <section definitions>
%% }
%%
%% Four sections are currently supported: \lowupcase, \lowercase, \uppercase
%% and \order. The syntax of the four supported sections is summarised below.
%%
%% 8-bit characters may be entered naturally, but to avoid problems with
%% character set translation or corruption, they can also be entered using
%% the TeX-style portable notation for character codes, i.e. ^^XX, where XX
%% is the hexadecimal value ofthe character code.
%%
%% Reading of the sections ends when the first '}' character is reached, so
%% '}' can't be included in a section. You can't use ^^7d either.
%%
%% The percent sign ('%') is used to introduce a trailing comment - it and
%% all remaining characters on a line are ignored. ^^25 has the same effect.
%%
%%
%% \lowupcase section
%%
%% The \lowupcase section of the CS file is used to define the lower
%% /upper and upper/lower case relationship of pairs of specified
%% characters. It is only used if the relationship is symmetrical - use
%% \lowercase or \upcase if it isn't.
%%
%% The syntax of the \lowupcase section is:
%%
%% \lowupcase{
%% <LC-1> <UC-1> % Comment begins with a percent sign
%% <LC-2> <UC-2>
%% ...
%% <LC-N> <UC-N>
%% }
%%
%% Each <LC-n> <UC-n> pair of characters defines that the upper case
%% equivalent of <LC-n> is <UC-n> *and* the lower case equivalent of
%% <UC-n> is <LC-n>.
%%
%% You cannot redefine the lower or upper case equivalent of an ASCII
%% character (code < 128), so all instances of <LC-n> and <UC-n>
%% (i.e. both sides of the relationship) must have codes > 127.
%%
%%
%% \lowercase section
%%
%% The \lowercase section of the CS file is used to define the lower case
%% equivalent of specified characters. It should normally only be used
%% if the relationship isn't symmetrical - use \lowupcase if it is.
%%
%% The syntax of the \lowercase section is:
%%
%% \lowercase{
%% <UC-1> <LC-1> % Comment begins with a percent sign
%% <UC-2> <LC-2>
%% ...
%% <UC-N> <LC-N>
%% }
%%
%% Each <LC-n> <UC-n> pair of characters defines that the lower case
%% equivalent of <UC-n> is <LC-n>.
%%
%% You cannot redefine the lower case equivalent of an ASCII character
%% (code < 128), so all instances of <UC-n> (i.e. the left hand side
%% of the relationship) must have codes > 127.
%%
%%
%% \uppercase section
%%
%% The \uppercase section of the CS file is used to define the upper case
%% equivalent of specified characters. It should normally only be used
%% if the relationship isn't symmetrical - use \lowupcase if it is.
%%
%% The syntax of the \uppercase section is:
%%
%% \uppercase{
%% <LC-1> <UC-1> % Comment begins with a percent sign
%% <LC-2> <UC-2>
%% ...
%% <LC-N> <UC-N>
%% }
%%
%% Each <LC-n> <UC-n> pair of characters defines that the upper case
%% case equivalent of <LC-n> is <UC-n>.
%%
%% You cannot redefine the upper case equivalent of an ASCII character
%% (code < 128), so all instances of <LC-n> (i.e. the left hand side
%% of the relationship) must have codes > 127.
%%
%%
%% \order section
%%
%% The \order section of the CS file is used to define the order in which
%% characters are sorted.
%%
%% The syntax of the \order section is:
%%
%% \order{
%% <char-1> % Comment begins with a percent sign
%% <char-2> <char-3> % whitespace between the chars
%% <char-4> - <char-5> % a hyphen between the chars
%% <char-4> _ <char-5> % an underscore between the chars
%% ...
%% <char-n>
%% }
%%
%% All characters on the same line are given the same sorting weight.
%%
%% The construct <char-1> <underscore> <char-2> is used to denote that
%% all characters in the range <char-1> to <char-2> should be given the
%% same sorting weight. For example, "A _ Z" would cause all ASCII
%% upper case alphabetical characters to have the same sorting weight
%% and would be equivalent to placing all 26 characters on the same line.
%%
%% The construct <char-1> <hyphen> <char-2> is used to denote that all
%% characters in the range <char-1> to <char-2> should be given an
%% ascending set of sorting weights, starting with <char-1> and ending
%% with <char-2>. For example, "A - Z" would cause all upper case ASCII
%% alphabetical characters to be sorted in ascending order and would be
%% equivalent to placing 'A' on the first line, 'B' on the second,
%% through to 'Z' on the 26th line.
%%
%% The characters at the beginning of the order section are given a lower
%% sorting weight than characters occuring later. When sorting
%% alphabetically, characters with the lowest weight come first.
%%
%% All characters not in the \order section (including ASCII characters)
%% are given the same very high sorting weight to ensure that they come
%% last when sorting alphabetically.

%%
%% CHARACTER SET
%%
%% There are no character codes > 127 in ASCII, so we don't need \lowupcase,
%% \lowercase or \uppercase sections.
%%
%%
%% SORTING ORDER
%%
%% The sorting order defined is the natural English language sorting order
%% (i.e. 0..9AaBb..YyZz). Any other characters will be sorted after the
%% characters in the \order section.
