Japanese charset with cfdocument

Hi, I know this problem has happened before, but after all the research and follow all the things I can do, I still stuck.

so this is my code:

<cfquery>

select a, b

from table 1

</cfquery>

<cfdocument format = "flashpaper">

<cfoutput>

#a#, #b#

</cfoutput>

Nothing fancy. however, a and b are in Japanese font. the HTML file display the character just fine, as do the excel format.

I change my jvm.config with "-Duser.language=ja -Duser.region=JP". I also edit the cffont.properties to be the same with cffont.properties.ja

I also install the Japanese support fornt pack for the server using "yum install "@Japanese support"

on Adobe reader, I also install Asian support language pack.

The result still the same when I run the code, the japanese character returns as boxes.

I am not sure what else to do so my character come out correctly.

I am using Centos 6, coldfusion 10 - developer edition, and postgres 9, my database has UTF-8

Any suggestion? PLEASE!!!
