+@vindex gnus-newsgroup-maximum-articles
+In groups in some news servers, there might be a big gap between a few
+very old articles that will never be expired and the recent ones. In
+such a case, the server will return the data like @code{(1 . 30000000)}
+for the @code{LIST ACTIVE group} command, for example. Even if there
+are actually only the articles 1-10 and 29999900-30000000, Gnus doesn't
+know it at first and prepares for getting 30000000 articles. However,
+it will consume hundreds megabytes of memories and might make Emacs get
+stuck as the case may be. If you use such news servers, set the
+variable @code{gnus-newsgroup-maximum-articles} to a positive number.
+The value means that Gnus ignores articles other than this number of the
+latest ones in every group. For instance, the value 10000 makes Gnus
+get only the articles 29990001-30000000 (if the latest article number is
+30000000 in a group). Note that setting this variable to a number might
+prevent you from reading very old articles. The default value of the

+@node Non-ASCII Group Names
+@section Accessing groups of non-English names
+@cindex non-ascii group names
+
+There are some news servers that provide groups of which the names are
+expressed with their native languages in the world. For instance, in a
+certain news server there are some newsgroups of which the names are
+spelled in Chinese, where people are talking in Chinese. You can, of
+course, subscribe to such news groups using Gnus. Currently Gnus
+supports non-@acronym{ASCII} group names not only with the @code{nntp}
+back end but also with the @code{nnml} back end and the @code{nnrss}
+back end.
+
+Every such group name is encoded by a certain charset in the server
+side (in an @acronym{NNTP} server its administrator determines the
+charset, but for groups in the other back ends it is determined by you).
+Gnus has to display the decoded ones for you in the group buffer and the
+article buffer, and needs to use the encoded ones when communicating
+with servers. However, Gnus doesn't know what charset is used for each
+non-@acronym{ASCII} group name. The following two variables are just
+the ones for telling Gnus what charset should be used for each group:
+
+@table @code
+@item gnus-group-name-charset-method-alist
+@vindex gnus-group-name-charset-method-alist
+An alist of select methods and charsets. The default value is
+@code{nil}. The names of groups in the server specified by that select
+method are all supposed to use the corresponding charset. For example:
+
+@lisp
+(setq gnus-group-name-charset-method-alist
+ '(((nntp "news.com.cn") . cn-gb-2312)))
+@end lisp
+
+Charsets specified for groups with this variable are preferred to the
+ones specified for the same groups with the
+@code{gnus-group-name-charset-group-alist} variable (see below).
+
+A select method can be very long, like:
+
+@lisp
+(nntp "gmane"
+ (nntp-address "news.gmane.org")
+ (nntp-end-of-line "\n")
+ (nntp-open-connection-function
+ nntp-open-via-rlogin-and-telnet)
+ (nntp-via-rlogin-command "ssh")
+ (nntp-via-rlogin-command-switches
+ ("-C" "-t" "-e" "none"))
+ (nntp-via-address @dots{}))
+@end lisp
+
+In that case, you can truncate it into @code{(nntp "gmane")} in this
+variable. That is, it is enough to contain only the back end name and
+the server name.
+
+@item gnus-group-name-charset-group-alist
+@cindex UTF-8 group names
+@vindex gnus-group-name-charset-group-alist
+An alist of regexp of group name and the charset for group names.
+@code{((".*" . utf-8))} is the default value if UTF-8 is supported,
+otherwise the default is @code{nil}. For example:
+
+@lisp
+(setq gnus-group-name-charset-group-alist
+ '(("\\.com\\.cn:" . cn-gb-2312)
+ (".*" . utf-8)))
+@end lisp
+
+Note that this variable is ignored if the match is made with
+@code{gnus-group-name-charset-method-alist}.
+@end table
+
+Those two variables are used also to determine the charset for encoding
+and decoding non-@acronym{ASCII} group names that are in the back ends
+other than @code{nntp}. It means that it is you who determine it. If
+you do nothing, the charset used for group names in those back ends will
+all be @code{utf-8} because of the last element of
+@code{gnus-group-name-charset-group-alist}.
+
+There is one more important variable for non-@acronym{ASCII} group
+names. @emph{XEmacs users must set this}. Emacs users necessarily need
+not do:
+
+@table @code
+@item nnmail-pathname-coding-system
+The value of this variable should be a coding system or @code{nil}
+(which is the default). The @code{nnml} back end, the @code{nnrss} back
+end, the @acronym{NNTP} marks feature (@pxref{NNTP marks}), the agent,
+and the cache use non-@acronym{ASCII} group names in those files and
+directories. This variable overrides the value of
+@code{file-name-coding-system} which specifies the coding system used
+when encoding and decoding those file names and directory names.
+
+In XEmacs (with the @code{mule} feature), @code{file-name-coding-system}
+is the only means to specify the coding system used to encode and decode
+file names. Therefore, @emph{you, XEmacs users, have to set it} to the
+coding system that is suitable to encode and decode non-@acronym{ASCII}
+group names. On the other hand, Emacs uses the value of
+@code{default-file-name-coding-system} if @code{file-name-coding-system}
+is @code{nil}. Normally the value of
+@code{default-file-name-coding-system} is initialized according to the
+locale, so you will need to do nothing if the value is suitable to
+encode and decode non-@acronym{ASCII} group names.
+
+The value of this variable (or @code{default-file-name-coding-system})
+does not necessarily need to be the same value that is determined by
+@code{gnus-group-name-charset-method-alist} and
+@code{gnus-group-name-charset-group-alist}.
+
+If you want to subscribe to the groups spelled in Chinese but
+@code{default-file-name-coding-system} is initialized by default to
+@code{iso-latin-1} for example, that is the most typical case where you
+have to set @code{nnmail-pathname-coding-system} even if you are an
+Emacs user. The @code{utf-8} coding system is a good candidate for it.
+Otherwise, you may change the locale in your system so that
+@code{default-file-name-coding-system} may be initialized to an
+appropriate value, instead of specifying this variable.
+@end table
+
+Note that when you copy or move articles from a non-@acronym{ASCII}
+group to another group, the charset used to encode and decode group
+names should be the same in both groups. Otherwise the Newsgroups
+header will be displayed incorrectly in the article buffer.

+returns the data containing the pairs of a group and an article number
+in the @code{Xref} header. Gnus normally uses the article number to

+
+When Gnus expires your mail (@pxref{Expiring Mail}), it starts with a
+list of expirable articles and asks the IMAP server questions like ``Of
+these articles, which ones are older than a week?'' While this seems
+like a perfectly reasonable question, some IMAP servers take a long time
+to answer it, since they seemingly go looking into every old article to
+see if it is one of the expirable ones. Curiously, the question ``Of
+@emph{all} articles, which ones are newer than a week?'' seems to be
+much faster to answer, so setting this variable causes Gnus to ask this
+question and figure out the answer to the real question itself.
+
+This problem can really sneak up on you: when you first configure Gnus,
+everything works fine, but once you accumulate a couple thousand
+messages, you start cursing Gnus for being so slow. On the other hand,

+between Emacs and the local network looks alive even if the server has
+closed a connection for some reason (typically, a timeout).
+Consequently, Emacs continues waiting for a response from the server for
+the @code{LOGOUT} command that Emacs sent, or hangs in other words. If
+you are in such a network, setting this variable to a number of seconds
+will be helpful. If it is set, a hung connection will be closed
+forcibly, after this number of seconds from the time Emacs sends the
+@code{LOGOUT} command. It should not be too small value but too large

@item @acronym{NOV}
@cindex @acronym{NOV}
+@acronym{NOV} stands for News OverView, which is a type of news server
+header which provide datas containing the condensed header information
+of articles. They are produced by the server itself; in the @code{nntp}
+back end Gnus uses the ones that the @acronym{NNTP} server makes, but
+Gnus makes them by itself for some backends (in particular, @code{nnml}).
+
When Gnus enters a group, it asks the back end for the headers of all
unread articles in the group. Most servers support the News OverView
format, which is more compact and much faster to read and parse than the
normal @sc{head} format.
+The @acronym{NOV} data consist of one or more text lines (@pxref{Text
+Lines, ,Motion by Text Lines, elisp, The Emacs Lisp Reference Manual})
+where each line has the header information of one article. The header
+information is a tab-separated series of the header's contents including
+an article number, a subject, an author, a date, a message-id,
+references, etc.
+
+Those data enable Gnus to generate summary lines quickly. However, if
+the server does not support @acronym{NOV} or you disable it purposely or
+for some reason, Gnus will try to generate the header information by
+parsing each article's headers one by one. It will take time.
+Therefore, it is not usually a good idea to set nn*-nov-is-evil
+(@pxref{Slow/Expensive Connection}) to a non-@code{nil} value unless you
+know that the server makes wrong @acronym{NOV} data.
