 If you can't modify that file directly, copy it to the directory
 ~/.m17n.d/ (create it if it doesn't exist), and apply the patch.
 
+** Emacs running on GNU/Linux system with the m17n library Ver.1.7.1 or the
+earlier version has a problem with rendering Lao script with OpenType font.
+
+The problem can be fixed by installing the newer version of the m17n
+library (if any), or by following this procedure:
+
+1. Locate the file LAOO-OTF.flt installed on your system as part of the
+m17n library.  Usually it is under the directory /usr/share/m17n.
+
+2. Apply the following patch to LAOO-OTF.flt
