Problems with non-ascii characters in WireMail

[BitPoet]

Short description of the issue

Umlauts (non-ascii characters) used in the body or subject of messages sent using WireMail appear mangled.

Expected behavior

Umlauts should display as entered.

Actual behavior

Umlauts display as two characters with their raw ascii representation.

Optional: Suggestion for a possible fix

The text and html body parts should always be sent using quoted-printable encoding. This way, even old 7bit-only smtp server won't have any problems in accepting and relaying the mail. Other possible 7bit-compatible encodings like base64 obfuscate too much of the content for debugging purposes.

The subject line and the name parts in the from: and to: header fields should similarly be encoded using quoted printable, enabling the use of utf-8 characters there as well.
