+# Bug#19855907 IO THREAD AUTHENTICATION ISSUE WITH SOME CHARACTER SETS
+# Problem: IO thread fails to connect to master if servers are configured with
+# special character sets like utf16, utf32, ucs2.
+#
+# Analysis: MySQL server does not support few special character sets like
+# utf16,utf32 and ucs2 as "client's character set"(eg: utf16,utf32, ucs2).
+# When IO thread is trying to connect to Master, it sets server's character
+# set as client's character set. When Slave server is started with these
+# special character sets, IO thread (a connection to Master) fails because
+# of the above said reason.
+#
+# Fix: If server's character set is not supported as client's character set,
+# then set default's client character set(latin1) as client's character set.
