Can we please not use emoji in patch descriptions?

[Matt Mackall]

For future reference, not only are the bulk of emoji characters not
available in the (otherwise quite complete) fonts used by my desktop
email reader or terminal, they confuse my patch acceptance tool into
creating patches with names like "-16.patch" rather than something
useful like "7-mail-actually-use-the-verifycert-config-value.patch".

So now I've got a ton of confusing garbage hex code boxes in my inbox
such that everything looks like one giant spammy patch series and I've
also got a bunch of meaningless names in my patch directory as well.

And none of that is worth spending any free time trying to fix.

If we're going to add meaningless data to patch subjects, may I suggest:

- Pokemon names
- rail stations in Wales
- sound effects from the classic live-action Batman
- famous Hodor quotes

(It's frankly miraculous that I haven't already consigned every email
with a subject outside of Latin1 to /dev/null, because it's one of the
surest signs something is spam in my world.)
