How to send a special character in a SMS?

Hi Everybody,

I’m not sure of the explanation given by FAQ_poster.

I’m having a problem with character ° (degree Celsius), which is not displayed in phonebook or SMS.

Following the procedure I should set

at+wccs=1,0,176

1B
ctrl-z

Is it correct?

Why evey char has to be mapped to 1b?

What is the role of tables 1 and 2 in wccs command?

Unfortunately documentation lack of clarity (examples too) about this command.

Thank you for assistance

Best Regards,
Davide Tasca
