What does utf mean on mail

In the context of email, "UTF" stands for "Unicode Transformation Format". It's a character encoding standard that allows for the representation of a wide range of characters from different languages and scripts.

In email, UTF is used to specify the character encoding of the text in the email message. This is important because different email clients and devices may use different character encodings to display the text, and UTF helps to ensure that the text is displayed correctly.

There are several types of UTF encodings, including:

• UTF-8: This is the most commonly used UTF encoding, which uses a variable-length encoding scheme to represent Unicode characters.
• UTF-16: This encoding scheme uses 16-bit code units to represent Unicode characters.
• UTF-32: This encoding scheme uses 32-bit code units to represent Unicode characters.

When you see "UTF" in an email, it usually means that the email is encoded using one of these UTF encodings. For example, you might see "UTF-8" or "UTF-16" in the email headers or subject line.

Here are some common examples of what "UTF" might look like in an email:

• "Content-Type: text/plain; charset=UTF-8"
• "Content-Type: text/html; charset=UTF-16"
• "Subject: UTF-8 encoded text"

In general, UTF is used to ensure that email messages can be sent and received correctly across different devices and platforms, and to allow for the use of non-ASCII characters in email messages.
