Help to understand the encoding types

Dear Kannel Developers.

>From the user guide:
http://kannel.org/download/kannel-userguide-snapshot/userguide.html#AEN4179

I'd like learn to send these coding types using Kannel. Any help on
understanding the spec correctly appreciated. I sent this to the users list,
but have not yet received any response.

1)Is this correct?
For GSM alphabet which has coding of 7bits
 - use coding = 0 & charset = ISO-8859-1
For ISO-8859-1 (Latin1) which has coding of 7bits
 - use coding = 0 & charset = ISO-8859-1
For Unicode which has coding of 8bits
 - use coding = 1 & charset = UTF-16BE
For UCS2 which has coding UCS-2
  - use coding = 2 & charset = UTF-16BE

2)For ringtones or Logos is this correct?
 set udh for the ringtone or logo and coding is set to 8bits
 - use coding = 1 & charset = UTF-16BE

3)When do you use alt-dcs? When do you use FX and 0X?
>From the User Guide "Optional. If unset, Kannel uses the alt-dcs defined on
smsc configuration, or 0X per default. If equals to 1, uses FX. If equals to
0, force 0X."

Wishing the Kannel developers list seasons greetings and a prosperous 2006.
I'd also like to thank the Kannel developers for giving the Kannel community
such a great product.
