+# 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

+# 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

+# 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.

+    Returns string representation of this item in ASCII format.
+
+    SYNOPSIS
+      val_str_ascii()
+      str - similar to val_str();
+
+    NOTE
+      This method is introduced for performance optimization purposes.
+
+      1. val_str() result of some Items in string context
+      depends on @@character_set_results.
+      @@character_set_results can be set to a "real multibyte" character
+      set like UCS2, UTF16, UTF32. (We'll use only UTF32 in the examples
+      below for convenience.)
+
+      So the default string result of such functions
+      in these circumstances is real multi-byte character set, like UTF32.
+
+      For example, all numbers in string context
+      return result in @@character_set_results:
+
+      SELECT CONCAT(20010101); -> UTF32
+
+      We do sprintf() first (to get ASCII representation)
+      and then convert to UTF32;
+      
+      So these kind "data sources" can use ASCII representation
+      internally, but return multi-byte data only because
+      @@character_set_results wants so.
+      Therefore, conversion from ASCII to UTF32 is applied internally.
+
+
+      2. Some other functions need in fact ASCII input.
+
+      For example,
+        inet_aton(), GeometryFromText(), Convert_TZ(), GET_FORMAT().
+
+      Similar, fields of certain type, like DATE, TIME,
+      when you insert string data into them, expect in fact ASCII input.
+      If they get non-ASCII input, for example UTF32, they
+      convert input from UTF32 to ASCII, and then use ASCII
+      representation to do further processing.
+
+
+      3. Now imagine we pass result of a data source of the first type
+         to a data destination of the second type.
+
+      What happens:
+        a. data source converts data from ASCII to UTF32, because
+           @@character_set_results wants so and passes the result to
+           data destination.
+        b. data destination gets UTF32 string.
+        c. data destination converts UTF32 string to ASCII,
+           because it needs ASCII representation to be able to handle data
+           correctly.
+
+      As a result we get two steps of unnecessary conversion:
+      From ASCII to UTF32, then from UTF32 to ASCII.
+
+      A better way to handle these situations is to pass ASCII
+      representation directly from the source to the destination.
+
+      This is why val_str_ascii() introduced.

-
-  SYNOPSIS
-    my_strnncollsp_ucs2()
-    cs                  character set handler
-    a                   First string to compare
-    a_length            Length of 'a'
-    b                   Second string to compare
-    b_length            Length of 'b'
-
-  IMPLEMENTATION
-    If one string is shorter as the other, then we space extend the other
-    so that the strings have equal length.
-
-    This will ensure that the following things hold:
-
-    "a"  == "a "
-    "a\0" < "a"
-    "a\0" < "a "
-
-  RETURN
-    < 0  a <  b
-    = 0  a == b
-    > 0  a > b

+
+  IMPLEMENTATION
+    If one string is shorter as the other, then we space extend the other
+    so that the strings have equal length.
+
+    This will ensure that the following things hold:
+
+    "a"  == "a "

+    "a\0" < "a "
