Incorrect word wrapping in outgoing plaintext messages

[Roman Imankulov]

There is a closed bug #1484148 about overlength lines in plaintext messages.

Unfortunately, the fix provided does not cover multibyte strings due to PHP wordwrap() function nature, which works only with single-byte encodings (used in rcmail_wrap_quoted() function). This results in too short lines with non-latin characters (reproduced on any non-latin UTF-8 messages).

Conceptually I see at least two alternative solutions:

1. Use one of the bypass functions which may be found in the comments here: http://php.net/wordwrap
2. Use the custom Content-Transfer-Encoding and encode message body (i.e. encode message text with base64 and use "Content-Transfer-Encoding: base64").

I think the second option is more preferable because it does not insert unrequested line breaks in the message body and generates pure ASCII message.
