+# Bug 1264
+#
+# Description: 
+#
+# When using a ucs2 table in MySQL, 
+# either with ucs2_general_ci or ucs2_bin collation,
+# words are returned in an incorrect order when using ORDER BY
+# on an _indexed_ CHAR or VARCHAR column. They are sorted with
+# the longest word *first* instead of last. I.E. The word "aardvark"
+# is in the results before the word "a".
+#
+# If there is no index for the column, the problem does not occur.
+#
+# Interestingly, if there is no second column, the words are returned
+# in the correct order. 
+#
+# According to EXPLAIN, it looks like when the output includes columns that
+# are not part of the index sorted on, it does a filesort, which fails. 
+# Using a straight index yields correct results.
+
+
+#
+# Two fields, index
+#
