Ah Thanks...
That's in /roundcube/program/steps/mail/sendmail.inc
Attached two pics, mailone is how the mail shows in Roundcube, mailtwo is how the mail shows in the Type Android email app.
This is in the header of the received email:
Content-Type: text/plain; charset=utf-8; format=flowed
Content-Transfer-Encoding: 7bit
Don't know if it has anything to do with 7 or 8 bit, but since all my other email programs seem to use 8bit and UTF-8, I thought using this as my default for sending email, may solve this.

Anyways, my default is now 8bit and UTF-8, we will see.
