 Note that there are some limitations on using this extension:
 
 - You should use single encoding in one repository.
-- You should set same encoding for the repository by locale or
-  HGENCODING.

+
+By default, win32mbcs uses encoding.encoding decided by mercurial.
+You can specify the encoding by config option.
 
-Path encoding conversion are done between Unicode and
-encoding.encoding which is decided by Mercurial from current locale
-setting or HGENCODING.
