Stop Splitting Surrogates

[theck13]

Fix

This is the Android counterpart of Simperium/node-simperium#91 and Simperium/simperium-ios#582. These changes stop the splitting of surrogate pairs, which resulted in corrupted data in note content.

Review

Only one developer is required to review these changes, but anyone can perform the review.

Thanks for patching this. In testing this gave us the notes we wanted.

Do we have a beta channel to get this out into testing before sending it to everyone?

When we update the com.simperium.android:simperium dependency in Simplenote, it will be included in the next code freeze. Following the code freeze, Simplenote will be released to our beta testers where they can test for two weeks before we release to everyone.
