EUDC words can't show on RemoteApp

hello

I am using 2008 R2, and I have a application written by foxpro.

I use it through RemoteApp, and it works very well.

But I have some EUDC words can't show on RemoteApp,and these words show correctly on Remote Desktop (by execute that foxpro application manually.)

I had installed the hotfix but problem still there.  http://support.microsoft.com/kb/979580/en-us



Can anyone help me?

Thank You.
