alt-charset on HTTP SMSCs

[Nii Ako Ampa-Sowa]

Hello,

Does anyone have experience with converting between different character
encoding schemes for HTTP SMSCs? 

Here's the scenario I'm facing: I receive messages via SMPP interface in
encoded as UCS-2. I need to send these messages out formatted as UTF-8
to an HTTP SMSC. 

For some reason defining the alt-charset as UTF-8 (or anything else, for
that matter) doesn't seem to have an effect on what is sent out in the
HTTP call. Does the alt-charset directive work with HTTP SMSCs?

Any help will be greatly appreciated.

Thanks,

Nii.
