@node Non-ASCII Characters, Searching and Matching, Text, Top
Emacs buffers and strings support a large repertoire of characters
from many different scripts, allowing users to type and display text
-in most any known written language.
+in almost any known written language.
@cindex character codepoint
@cindex codespace
The representation for a string is determined and recorded in the string
when the string is constructed.
-@defopt enable-multibyte-characters
+@defvar enable-multibyte-characters
This variable specifies the current buffer's text representation.
If it is non-@code{nil}, the buffer contains multibyte text; otherwise,
it contains unibyte encoded text or binary non-text data.
You cannot set this variable directly; instead, use the function
@code{set-buffer-multibyte} to change a buffer's representation.
-
-The @samp{--unibyte} command line option does its job by setting the
-default value to @code{nil} early in startup.

@defun position-bytes position
Buffer positions are measured in character units. This function
characters.
@end defun
+@defun byte-to-string byte
+@cindex byte to string
+This function returns a unibyte string containing a single byte of
+character data, @var{character}. It signals a error if
+@var{character} is not an integer between 0 and 255.
+@end defun

@defun multibyte-char-to-unibyte char
This converts the multibyte character @var{char} to a unibyte
character, and returns that character. If @var{char} is neither
value is a string consisting of upper-case Latin letters A to Z,
digits, spaces, and hyphen @samp{-} characters.
+@cindex unicode general category
@item general-category
This property corresponds to the Unicode @code{General_Category}
property. The value is a symbol whose name is a 2-letter abbreviation
@var{propname} for the character @var{char}.
@end defun
-@defvar char-script-table
+@defvar unicode-category-table
The value of this variable is a char-table (@pxref{Char-Tables}) that
-specifies, for each character, a symbol whose name is the script to
-which the character belongs, according to the Unicode Standard
-classification of the Unicode code space into script-specific blocks.
-This char-table has a single extra slot whose value is the list of all
-script symbols.

+The value of this variable is a char-table that specifies, for each
+character, a symbol whose name is the script to which the character
