Today I tried to edit wiki page and I got following error:
Unhandled Exception ("AphrontCharacterSetQueryException") Attempting to construct a query containing characters outside of the Unicode Basic Multilingual Plane. MySQL will silently truncate this data if it is inserted into a `utf8` column. Use the `%B` conversion to escape binary strings data.
I'm currently working on phabricator based on git revision f2a343058581fa68ab7fc7fe7122aaccc7f2d0f0.
