[bug] clickatell unicode HTTP code for Kannel

Hi,

We have been testing with concatenated Unicode SMSs and decided to try the
Kannel code for Clickatell.  There seems to be a bug. Version of Kannel:
svn-r4850M
Has anyone found this bug and created a patch for it?
We also emailed this directly to Clickatell.
The HTTP Code for Clickatell works fine for a non-unicode SMS.
Unless there is patch, we would advise people to not send Unicode via
Clickatell and Kannel.

Message to convert to Unicode:
Sr Eduardo Seu seguro automóvel 4191 caduca 2011/01/08 para renovar contacte

Message sent directly to Kannel using the Clickatell HTTP code in Kannel:

From Kannel Logs: Bearerbox log we see (The password is replaced with

The unicode that Kannel generates and sends to Clickatell is incorrect.  
It looks like UTF8 but it's not (see the end of the unicode)

UTF-8:
