Configure the Control Center for single- and double-byte character sets and for appropriate number, date, and time settings with the Locale setting. For example, the Locale setting affects the format of email messages that the Control Center sends, such as notifications, alerts, and reports.
You can also select a fallback encoding option for the Control Center to use in cases when the language identification feature is unable to correctly determine the language of a quarantined email message.
Language identification may fail if the message headers or body contain any of the following items:
Raw 8-bit characters with missing or corrupted encoding information
Too few characters with missing or corrupted encoding information
Only a few characters with a mix of two or more types of encodings
Set the fallback encoding to the most common encoding that is used in your region or country.
