Notes:
1) Lowercase greek letters will be converted to their corresponding upper case letters. However, a greek letter with τόνο (ά ή έ etc) does not have uppercase letter so the specific letters will not appear in the message.
2) Some special characters like € count as 2 characters in SMS messages
3) Please note that GSM networks may not support multiple languages. If you send a non-latin message to recipients located at multiple countries or who are roaming, the SMS may not be delivered or may not appear correctly. Prefer to write an SMS in english.
