Talk:Signatures - Thunderbird
From MozillaZine Knowledge Base
I removed a couple of misunderstandings.
That is not how signatures work. Thunderbird reads the signature file into the editor. The editor works in Unicode, so it supports all characters. When Thunderbird sends the message, it encodes the entire message for transmission, including anything that might have originally come from the signature file. Therefore using any characters at all in your signature file is safe and complies with standards.
In Thunderbird, identities and accounts are not the same. A signature file is an identity setting, not an account setting. Unfortunately, Thunderbird's user interface does not make this clear. For more information, see: Mail concepts
