I've got problems with sending a mail formated in UTF-8. The is not recognized at all and the special characters of my language aren't displayed proprely...
The same thing append when I write the email in an HTML file and I open the .html file in web browser.
If I write the file in UTF-16BE I don't have any problem. The problem is that I only see UTF-8 (for the unicodes encodings) in the Thunderbird menu.
So, How I can set UTF-16?
