how to set character encoding in request?

[chaohua wang]

Hi Folks,

When i update a product name in catalog page, i sent request to back end. i
debugged in ContorlServlet.java file.
I  saw request.getCharacterEncoding() is null. I wonder if there is a way to
set CharacterEncoding in the request from front end?
update product file is EditPtoductContent.ftl

Thanks,

Chwang
