I'm not still sure about the details of conversion map used by
iconv. Japanese users have enough trouble with the conversin between
Unicode and othe charsets. This is because there are many variation of
conversion maps provided by vendors. For example, the conversion map
used for Unicode and SJIS in PostgreSQL has been carefully designed to
minimize problems described above. Another issue is the availabilty of
iconv among platforms. If we are sure that a particlular iconv
conversion routine is available on all platforms and the conversion
result is good eough, our conversion routine could be replaced by new
one using iconv.

Use a simple wrap function.
