   The value is a function to call after some text is inserted and
   decoded by the coding system itself and before any functions in
   `after-insert-functions' are called.  The argument of this
   function is the same as for a function in
   `after-insert-file-functions', i.e. LENGTH of the text inserted,
   with point at the head of the text to be decoded.

   o pre-write-conversion
- 
+
   The value is a function to call after all functions in
   `write-region-annotate-functions' and `buffer-file-format' are
   called, and before the text is encoded by the coding system itself.
   The arguments to this function are the same as those of a function
   in `write-region-annotate-functions', i.e. FROM and TO, specifying
   a region of text.

+
   o translation-table-for-decode
- 
+
   The value is a translation table to be applied on decoding.  See
   the function `make-translation-table' for the format of translation
   table.  This is not applicable to type 4 (CCL-based) coding systems.

   o translation-table-for-encode
-

   The value is a translation table to be applied on encoding.  This is
   not applicable to type 4 (CCL-based) coding systems.
-

   o safe-chars
- 
+
   The value is a char table.  If a character has non-nil value in it,
   the character is safely supported by the coding system.  This
   overrides the specification of safe-charsets.
