Hi When I attached a pdf to an email, the font on the pdf changes and becomes unreadable. When I use Outlook the pdf is perfect.

Thanks Julie

Hello there jlang4. We have read your message. We try to help you.

Some emails with strange symbols in their text can be solved by checking their settings in Thunderbird. It could be it for some reason stands on western code or other perhaps. Change them to Unicode to solve some strange characters.


Let me see for it in Thunderbird. A moment please.
