+commit ede390a0b18e4565abf8ac1e1ff717e1d43fc320
+Author: Paul Wankadia <junyer@chromium.org>
+Date:   Tue Apr 14 16:54:51 2020 +0000
+
+    Clean up a call to set_utf8().
+    
+    This is part of an effort to rewrite calls to utf8() and set_utf8()
+    (in RE2::Options) as calls to encoding() and set_encoding(),
+    respectively. utf8() and set_utf8() have been marked as the "legacy"
+    interface since 2008, so it is long past time that we get rid of them.
