-* Changes in Emacs Unicode
-
-** The Emacs character set is now a superset of Unicode.  
-(It has about four times the code space, which should be plenty).
-
-The internal encoding used for buffers and strings is now
-Unicode-based and called `utf-8-emacs'.  utf-8-emacs is backwards
-compatible with the UTF-8 encoding of Unicode.  The `emacs-mule'
-coding system can still read and write data in the old internal encoding.
-
-Since the internal encoding is also used by default for byte-compiled
-files -- i.e. the normal coding system for byte-compiled Lisp files is
-now utf-8-Emacs -- Lisp containing non-ASCII characters which is
-compiled by Emacs 23 can't be read by earlier versions of Emacs.  Files
-compiled by Emacs 20, 21, or 22 are loaded correctly as emacs-mule
-(whether or not they contain multibyte characters), which makes loading
-them somewhat slower than Emacs 23-compiled files.  Thus it may be worth
-recompiling existing .elc files which don't need to be shared with older
-Emacsen.
-
-** There are assorted new coding systems/aliases -- see M-x 
list-coding-systems.
-
-** New charset implementation with many new charsets.
-See M-x list-character-sets.  New charsets can be defined conveniently
-as tables of unicodes.
-
-The dimension of a charset is now 1, 2, 3, or 4, and the size of each
-dimension is no longer limited to 94 or 96.
-
-A dynamic charset priority list is used to infer the charset of
-characters for display.
-
-** New minor mode Auto Composition Mode composes characters automatically
-when they are displayed.  This mode is globally on by default.
-
-** Emacs now supports local fonts (fonts installed in the same machine
-as Emacs is running) by freetype and fontconfig libraries.  On X, they
-are derived via Xft library with antialias support.  Fontconfig-like
-font names (e.g. monospace-12) are also accepted.
-
-** New language environments Chinese-GBK, Chinese-GB18030, Khmer,
-TaiViet.
-
-** The following facilities are obsolete:
-
-Minor modes: unify-8859-on-encoding-mode, unify-8859-on-decoding-mode
-
-
-* Lisp changes in Emacs Unicode
-
-** Character code, representation, and charset changes.
-
-Now character code space is 0x0..0x3FFFFF with no gap.  Among them,
-characters of code 0x0..0x10FFFF are Unicode characters of the same
-code points.  Characters of code 0x3FFF80..0x3FFFFF are raw 8-bit bytes.
-
-Generic characters no longer exist.  
-
-In buffer and string, characters are represented by UTF-8 byte
-sequence in a multibyte buffer/string.
-
-The concept of charset is changed.  A single character may belong to
-multiple charset (e.g. a-grave (U+00E0) belongs to charsets unicode,
-iso-8859-1, iso-8859-3, and etc).
-
-*** The new function `characterp' returns t if and only if the argument
-is a character.
-
-*** The new function `max-char' returns the maximum character code
-(currently it is #x3FFFFF).
-
-*** The functions `encode-char' and `decode-char' now accept any
-character sets.
-
-*** The function `define-charset' now accepts a completely different
-form of arguments (old-style arguments still work).
-
-*** The new function `define-charset-alias' defines an alias of a charset.
-
-*** The value of the function `char-charset' depends on the current
-priorities of charsets.
-
-*** The new function `charset-priority-list' returns the list of
-charsets ordered by priority.
-
-*** The new function `set-charset-priority' sets priorities of charsets.
-
-*** The new function `unibyte-charset' returns the current unibyte
-charset.  The unibyte charset determines how unibyte/multibyte
-conversion is done.
-
-*** The new function `set-unibyte-charset' sets the unibyte charset.
-
-*** The new function `unibyte-string' make a unibyte string from bytes.
-
-** Code conversion changes
-
-*** The new function `define-coding-system' should be used to define a
-coding system instead of `make-coding-system' (which is obsolete now).
-
-*** The functions `encode-coding-region' and `decode-coding-region'
-have an optional 4th argument to specify where the result of
-conversion should go.
-
-*** The functions `encode-coding-string' and `decode-coding-string'
-have an optional 4th argument specifying a buffer to store the result
-of conversion.
-
-*** The new function `with-coding-priority' executes the body part with
-the specified coding system priority order.
-
-*** The new function `check-coding-systems-region' checks if the text
-in the region is encodable by the specified coding systems.
-
-*** The new function `coding-system-aliases' returns a list of aliases
-of a coding system.
-
-*** The new function `coding-system-charset-list' returns a list of
-charsets supported by a coding system.
-
-*** The new function `coding-system-priority-list' returns a list of
-coding systems ordered by their priorities.
-
-*** Thew new function `set-coding-system-priority' sets priorities of
-coding systems.
-
-** Composition changes
-
-*** New functions and variables `auto-composition-mode' and
-`global-auto-composition-mode' toggles the new minor mode Auto
-Composition Mode locally and globally.
-
-*** New variable `auto-composition-function' is a function used in
-Auto Composition Mode to compose characters.  The default value is the
-function `auto-compose-chars'.
-
-** Font Backend changes.
-
-*** New frame parameter `font-backend' specifies a list of
-font-backends supported by the frame's graphic device.  On X, they are
-currently `x' and `xft'.
-
-*** New function `fontp' checks if the argument is a font-spec
-or font-entity.
-
-*** New function `font-spec' creates a new font-spec object.
-
-*** New function `font-get' returns a font property value.
-
-*** New function `font-put' sets a font property value.
-
-*** New function `list-fonts' returns a list of font-entities matching
-the given specification.
-
-*** New function `list-families' returns a list of family names of
-available fonts.
-
-*** New function `font-font' returns a font-entity best matching with
-the given specification.
-
-*** New function `font-xlfd-name' returns an XLFD name of a given font
-(font-spec, font-entity, or font-object).
-
-*** New function `clear-font-cache' clears all font caches.
-
-** The function get-char-code-property now accepts many Unicode base
-character properties.  They are `name', `general-category',
-`canonical-combining-class', `bidi-class', `decomposition',
-`decimal-digit-value', `digit-value', `numeric-value', `mirrored',
-`old-name', `iso-10646-comment', `uppercase', `lowercase', and
-`titlecase'.
-
-** The new function `define-char-code-property' defines a character
-code property.
-
-** The new function `char-code-property-description' returns the
-description string of a character code property.
-
-*** The new variable `find-word-boundary-function-table' is a
-char-table of functions to search for a word boundary.
-
-*** The new variable `char-script-table' is a char-table of script names.
-
-*** The new variable `char-width-table' is a char-table of character widths.
-
-*** The new variable `print-charset-text-property' controls how to
-handle `charset' text property on printing a string.
-
-*** The new variable `printable-chars' is a char-table defining if a
-character is printable or not.
-
-*** The new function `robin-define-package' defines a Robin package,
-which is an input method system different from Quail.
-
-*** The new function `robin-modify-package' modifies an existing Robin package.
-
-*** The new function `robin-use-package' start using a Robin package
-as an input method.
-
-** The functions `modify-syntax-entry' and `modify-category-entry' now
-accepts a cons of characters as the first argument, and modify all
-entries in that range of characters.
-
-** The function `set-fontset-font' now accepts a script name as the
-second argument, and has an optional 5th argument to control how to
-set the font.
-
-** The functions `char-bytes', `chars-in-region', `set-coding-priority',
-`make-coding-system', and `char-valid-p' are now obsolete.
-
-
-* Incompatible Lisp changes
-
-** The behavior of map-char-table has changed.  It may call the
-specified function with a cons (FROM . TO) as a key if characters in
-that range have the same value.
-
-** The value of the function `charset-id' is now always 0.
-
-** The functions `register-char-codings' and `coding-system-spec' are deleted.
-
-** Many codepage related functions are removed.  They are:
-  cp-make-coding-systems-for-codepage, cp-charset-for-codepage,
-  cp-language-for-codepage, cp-offset-for-codepage,
-  cp-supported-codepages
-You don't need them anymore because coding systems created by these
-functions are supported from the start now.
