Shall be merged after htmlmaid declares utf8.

HTMLMaid has a default fallback for string inputs, where a default DOM
is built around the input. It missed a charset setting, and so the
system kind of picked a default charset which screwed UTF-8 Markdown
Input pretty bad. When it is fixed, we should jump directly to this
upcoming release.
Typo.
Merge pull request #755 from doertedev/master
