problem reading an application parameter

Hello, SDN!

I wanna retrieve an application parameter, but i have some troubles with cyrillic encoding:

String param = WDProtocolAdapter.getProtocolAdapter().getRequestObject().getParameterValues("myparam");

param does not contain right data,

if i print param with IWDMessageManager, its displays some squares instead of the text.

I have tried to change encoding with help of

URLDecoder.decode(department, "UTF-8")

So, somebody can help?
