;;; Code
;; This file will work with both Emacs (>=20.3) and XEmacs (>=21). In
;; the following `Emacs' is used for both Emacs and XEmacs except where
;; it differs.
;; XXX: Thai stuff not yet ported to XEmacs. I don't know whether it
;; makes sense currently to support it because the Thai implementation
;; in XEmacs (version 21.1 and probably the upcoming 21.2) is not
;; complete: For example, there is no correct display handling of IR
;; 166 (this is the right part of TIS-620) in an ISO-2022 data stream,
;; decomposition of precomposed Thai (in xtis character set) doesn't
;; provide linguistic properties, etc.
;; The following tables map from Emacs's character sets to LaTeX2e
;; macros. Note that not all macros defined here really do exist. See
;; MULEenc.sty and cjk-enc.txt for further details.
;;
;; MULEenc.sty makes TeX character 0x7F `active' and assigns to it a
;; multiplex command which executes its first argument. To make the
;; macro expansion robust against \uppercase and \lowercase, only
;; numbers are used as parameters which index the various commands.
;;
;; 0x7F will be used as a parameter delimiting character also.
