Japanese characters in Velocity Context

Hi All,

I've generally had success with getting Velocity to print out Japanese 
characters when they appear in velocity templates, however recently when 
trying to place japanese characters in a Velocity context for use in 
adding data to a template, I have not been so fortunate.

I have tried various combinations of input.enoding and output.encoding 
trying UTF8, Shift_JIS and MS932.

Not of the Japanese characters added through the context have come out 
(I get just ????), and the japanese characters in the templates 
themselves only appear legibly when I leave out both input and output 
encodings, or set the output encoding to Shift_JIS.  Any other setting 
causes both the context based Japanese characters and the template based 
Japanese characters to become series of question marks.

I should also mention that I am using velocity as part of the turbine tdk.

If anybody has any insight about how I can pass Japanese characters 
through the velocity context I would be very grateful.
