Title: Prevent quoted_printable_encode from corrupting multibyte characters by splitting them between lines

Fixes https://bugs.php.net/bug.php?id=62462

`quoted_printable_encode` ignores multibyte characters when adding soft line breaks. If such break is inserted in the middle of multibyte char it corrupts the encoded string - this pull request fixes that.
