# Debug Message Content

The **Debug Message Content** option allows you to analyze the SMS by breaking it down into individual characters to check their type and impact on the message length. The results show a detailed classification of characters by type and how they affect the available character count for one SMS. Use this option to test your message content and ensure it is correctly formatted before sending.

Legend:

* **A - Permitted Characters:** Standard GSM-7 characters, counted as 1 character.
* **B - Extended GSM-7 Characters:** Less common characters, counted as 2 characters.
* **C - Diacritic Characters: Characters** with diacritics (e.g., "ą", "õ" ,“ç”), reduce available SMS length and are counted as 1 character.
* **D - UTF-8 Characters:** Non-GSM-7 characters, counted as 1 character but shorten message length.
* **E - Emojis:** Counted as 2 characters; reduce the available SMS length.

At the end, the system will ask if you want to send a message containing special characters. You must select **Yes** or **No** based on your preference.
