Thanks Robert,

From this, I found that my problem can be solved by upgrade my ruby from 
version 1.8.6 to ruby 1.8.7 or higher.

Let's see the ChangeLog of Ruby1.8.7
(http://svn.ruby-lang.org/repos/ruby/tags/v1_8_7_160/ChangeLog)
Mon Apr 14 13:58:32 2008  Akinori MUSHA  <knu@iDaemons.org>

  * string.c (rb_str_each_char): New methods: String#chars and
    #each_char; backported from 1.9.


And the ChangeLog of Ruby1.8.6
Mon Mar 27 22:19:09 2006  NARUSE, Yui  <naruse@ruby-lang.org>

  * ext/nkf/nkf-utf8/{nkf.c, utf8tbl.c, config.h}: imported nkf 2.0.6.
    * Add --ic / --oc option and mapping tables.
    * Add fallback option.
    * Add --no-best-fit-chars option.
