;; About ps-mule
;; -------------
;;
;; This package is used for ps-print to print multi-byte buffer.
;;
;; See also ps-print.el.
;;
;;
;; Printing Multi-byte Buffer
;; --------------------------
;;
;; The variable `ps-multibyte-buffer' specifies the ps-print multi-byte buffer
;; handling.
;;
;; Valid values for `ps-multibyte-buffer' are:
;;
;;  nil			    This is the value to use the default settings;
;;			    by default, this only works to print buffers with
;;			    only ASCII and Latin characters.   But this default
;;			    setting can be changed by setting the variable
;;			    `ps-mule-font-info-database-default' differently.
;;			    The initial value of this variable is
;;			    `ps-mule-font-info-database-latin' (see
;;			    documentation).
;;
;;  `non-latin-printer'	    This is the value to use when you have a japanese
;;			    or korean PostScript printer and want to print
;;			    buffer with ASCII, Latin-1, Japanese (JISX0208 and
;;			    JISX0201-Kana) and Korean characters.  At present,
;;			    it was not tested with the Korean characters
;;			    printing.  If you have a korean PostScript printer,
;;			    please, test it.
;;
;;  `bdf-font'		    This is the value to use when you want to print
;;			    buffer with BDF fonts.  BDF fonts include both latin
;;			    and non-latin fonts.  BDF (Bitmap Distribution
;;			    Format) is a format used for distributing X's font
;;			    source file.  BDF fonts are included in
;;			    `intlfonts-1.2' which is a collection of X11 fonts
;;			    for all characters supported by Emacs.  In order to
;;			    use this value, be sure to have installed
;;			    `intlfonts-1.2' and set the variable
;;			    `bdf-directory-list' appropriately (see ps-bdf.el
;;			    for documentation of this variable).
;;
;;  `bdf-font-except-latin' This is like `bdf-font' except that it uses
;;			    PostScript default fonts to print ASCII and Latin-1
;;			    characters.  This is convenient when you want or
;;			    need to use both latin and non-latin characters on
;;			    the same buffer.  See `ps-font-family',
;;			    `ps-header-font-family' and `ps-font-info-database'.
;;
;; Any other value is treated as nil.
;;
;; The default is nil.

  "Alist of charsets with the corresponding font information.
Each element has the form:

	(CHARSET (FONT-TYPE FONT-SRC FONT-NAME ENCODING BYTES) ...)

Where

CHARSET is a charset (symbol) for this font family,

FONT-TYPE is a font type: normal, bold, italic, or bold-italic.

FONT-SRC is a font source: builtin, bdf, vflib, or nil.

  If FONT-SRC is builtin, FONT-NAME is a built-in PostScript font name.

  If FONT-SRC is bdf, FONT-NAME is a BDF font file name, or a list of
  alternative font names.  To use this font, the external library `ps-bdf'
  is required.

  If FONT-SRC is vflib, FONT-NAME is the name of a font that VFlib knows.
  To use this font, the external library `vflib' is required.

  If FONT-SRC is nil, a proper ASCII font in the variable
  `ps-font-info-database' is used.  This is useful for Latin-1 characters.

ENCODING is a coding system to encode a string of characters of CHARSET into a
proper string matching an encoding of the specified font.  ENCODING may be a
function that does this encoding.  In this case, the function is called with
one argument, the string to encode, and it should return an encoded string.

BYTES specifies how many bytes each character has in the encoded byte
sequence; it should be 1 or 2.

All multi-byte characters are printed by fonts specified in this database
regardless of a font family of ASCII characters.  The exception is Latin-1
characters which are printed by the same font as ASCII characters, thus obey
font family.
