but not collation.
The problem here was that text literals in a view were always
dumped with character set introducer. That lead to loosing
collation information.
The fix is to dump character set introducer only if it was
in the original query. That is now possible because there
is no problem any more of loss of character set of string
literals in views -- after WL#4052 the view is dumped
in the original character set.

Since, as of MySQL 5.0.15, CHAR() arguments larger than 255 are converted into multiple result bytes, a single CHAR() argument can now take up to 4 bytes. This patch fixes Item_func_char::fix_length_and_dec() to take this into account.
This patch also fixes a regression introduced by the patch for bug21513. As now we do not always have the 'name' member of Item set for Item_hex_string and Item_bin_string, an own print() method has been added to Item_hex_string so that it could correctly be printed by Item_func::print_args().

LOCATE(str,NULL) IS NULL erroneously was evaluated to FALSE.
This happened because the Item_func_locate::fix_length_and_dec

the function item to 0. In consequence of this the function
was considered as the one that could not ever return NULL.

The function CRC32() returns unsigned integer.
But the metadata (the unsigned flag) for the
function was set incorrectly.
As a result type arithmetics based on the
function's metadata (like finding the concise
type of an temporary table column to hold the result)
returned incorrect results.
Fixed by returning correct type information.
This fix is based on code contributed by Martin Friebe
(martin@hybyte.com) on 2007-03-30.

When the SUBSTRING() function was used over a LONGTEXT field the max_length of
the SUBSTRING() result was wrongly calculated and set to 0. As the max_length
parameter is used while tmp field creation it limits the length of the result
field and leads to printing an empty string instead of the correct result.
Now the Item_func_substr::fix_length_and_dec() function correctly calculates
the max_length parameter.

The Item_func::print method was used to print the Item_func_encode and the
Item_func_decode objects. The last argument to ENCODE and DECODE functions
is a plain C string and thus Item_func::print wasn't able to print it.
The print() method is added to the Item_func_encode class. It correctly
prints the Item_func_encode and the Item_func_decode objects.

Bug#23409: Arguments of the ENCODE() and the DECODE() functions were not printed correctly.
The print() method is added to the Item_func_encode class. It correctly
prints the Item_func_encode and the Item_func_decode objects.
Handling of large signed/unsigned values was not consistent, so some string functions could return bogus results.
The current fix is to simply patch up the val_str() methods for those string items.
It would be good clean this code up in general, to make similar problems much harder to make. This is left as an exercise for the reader.
