In this case not, but actually the Date line is not an issue.  Anyway
the patch is malformed, please try to save your posted patch and apply
with git am and see how finally the commit message looks like.

I can't see any need for special characters in the patch itself.
Please submit the patch in a way that it can be applied properly with
patchwork client (or git am).

I would suggest switching to git send-email, then issues like
above could be easily avoided.
