[thelist] http -> sms, character coding

[Kasimir K]

Hello,

I'm working on an application which uses http to sms gateway. As the 
system will be used in many European countries, there's the national 
character issue. For instance here: 
http://www.dreamfabric.com/sms/default_alphabet.html
is a nice table of the sms 7 bit alphabet.

The content that is sent out is managed with a CMS, where the authors 
throw in all obscure national characters they can come up with...

So I have to filter the messages I'm sending to the gateway.

Then to my questions:
- Any ideas how to do the character filtering efficiently? There may be 
peak times, so speed is of essence here.
- Do all phones and operators handle the gsm alphabet in same way, or 
are the variations on this?
- Experiences and links would be appreciated, as this is my first 
sms-project...

¡muchas gracias!
