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. - - ----------------------------------------------------------------------- -This file is part of GNU Emacs. - -GNU Emacs is free software; you can redistribute it and/or modify -it under the terms of the GNU General Public License as published by -the Free Software Foundation; either version 2, or (at your option) -any later version. - -GNU Emacs is distributed in the hope that it will be useful, -but WITHOUT ANY WARRANTY; without even the implied warranty of -MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
