 @section Charsets
 @cindex charsets
 
-  Emacs defines most of popular character sets (e.g. ascii,
-iso-8859-1, cp1250, big5, unicode) as @dfn{charsets} and a few of its
-own charsets (e.g. emacs, unicode-bmp, eight-bit).  All supported
-characters belong to one or more charsets.  Usually you don't have to
-take care of ``charset'', but knowing about it may help understanding
-the behavior of Emacs in some cases.
-
-  One example is a font selection.  In each language environment,
-charsets have different priorities.  Emacs, at first, tries to use a
-font that matches with charsets of higher priority.  For instance, in
-Japanese language environment, the charset @code{japanese-jisx0208}
-has the highest priority (@pxref{Describe Language Environment}).  So,
-Emacs tries to use a font whose @code{registry} property is
-``JISX0208.1983-0'' for characters belonging to that charset.
-
-  Another example is a use of @code{charset} text property.  When
-Emacs reads a file encoded in a coding systems that uses escape
-sequences to switch charsets (e.g. iso-2022-int-1), the buffer text
-keep the information of the original charset by @code{charset} text
-property.  By using this information, Emacs can write the file with
-the same byte sequence as the original.
+  In Emacs, @dfn{charset} is short for ``character set''.  Emacs
+supports most popular charsets (such as @code{ascii},
+@code{iso-8859-1}, @code{cp1250}, @code{big5}, and @code{unicode}), in
+addition to some charsets of its own (such as @code{emacs},
+@code{unicode-bmp}, and @code{eight-bit}).  All supported characters
+belong to one or more charsets.
+
+  Emacs normally ``does the right thing'' with respect to charsets, so
+that you don't have to worry about them.  However, it is sometimes
+helpful to know some of the underlying details about charsets.
+
+  One example is font selection (@pxref{Font X}).  Each language
+environment (@pxref{Language Environments}) defines a ``priority
+list'' for the various charsets.  When searching for a font, Emacs
+initially attempts to find one that can display the highest-priority
+charsets.  For instance, in the Japanese language environment, the
+charset @code{japanese-jisx0208} has the highest priority, so Emacs
+tries to use a font whose @code{registry} property is
+@samp{JISX0208.1983-0}.
