+Introduction
+
+  I have tried the muntilingualization of w3m (w3m-m17n).
+  The patch for w3m-0.4.1 is available on the following site.
+
+    http://www2u.biglobe.ne.jp/~hsaka/w3m/index.html#m17n
+                                          patch/w3m-0.4.1-m17n-20030308.tar.gz
+                                          patch/README.m17n
+
+  It is a development version. And enough test is not preformed because
+  I can understand Japanese only. Please use, test, and report bugs.
+
+  Now, w3m-m17n has following functions.
+
+Supported encoding schemes (character set)
+
+  * Japanese
+      EUC-JP           - US_ASCII, JIS X 0208, JIS X 0201, JIS X 0212

+      UTF-8, UTF-7
+
+  NOTE:
+    * The left part of JIS X 0201 and GB 1988 (Chinese ASCII) are
+      treated as US_ASCII because they are used in tags of HTML document.
+      Another variant of US_ASCII is treated without change.
+    * JIS C 6226(old JIS) is treated as JIS X 0208.
+    * The sequence '~\n' of HZ is not supported.
+
+Display
+
+  There are two method for multilingual diplay.
+
+  (1) kterm + ISO-2022-JP/CN/KR
+
+    * kterm can handle JIS X 0213, CNS 11643, if the following patch
+      is applied.
+        http://www.st.rim.or.jp/~hanataka/kterm-6.2.0.ext02.patch.gz
+
+    * Specify the fontList for kterm with -fl option or in ~/.Xdefaults.
+    
+        -fl "*--16-*-jisx0213.2000-*,\
+             *--16-*-jisx0212.1990-0,\

+             *--16-*-cns11643.1992-*,\
+             *--16-*-iso8859-*"
+
+      Fonts of JIS X 0213 exist in
+        http://www.mars.sphere.ne.jp/imamura/jisx0213.html
+
+    * Set the "display_charset" to ISO-2022-JP(or ISO-2022-JP-2, KR, CN),
+      and "strict_iso2022" to OFF on the option pannel. (see below)
+
+  (2) xterm + UTF-8
+

+        http://www.clark.net/pub/dickey/xterm/xterm.html
+
+    * Fonts of Unicode exist in
+        http://www.cl.cam.ac.uk/~mgk25/ucs-fonts.html
+        http://openlab.ring.gr.jp/efont/index.html.en
+
+    * Use xterm with -u8 option.
+      The fonts are specified such as
+        -fn "*-medium-*--13-*-iso10646-1" \
+        -fb "*-bold-*--13-*-iso10646-1" \
+        -fw "*-medium-*-ja-13-*-iso10646-1"
+
+    * Set the "display_charset" to UTF-8.
+      And, it is better that "pre_conv" is ON.

+      (SO is assigned as `next-history'). If you want to use SI and SO,
+      press C-@(^@). After that, SI, SO, SS2, SS3, LS2, and LS3 of
