197782605f BUG#11338 (logging of prepared statement w/ blob type) 
In cp932, '\' character can be the second byte in a 
multi-byte character stream. This makes it difficult to use
mysql_escape_string. Added flag to indicate which languages allow
'\' as second byte of multibyte sequence so that when putting a prepared
statement into the binlog we can decide at runtime whether hex encoding
is really needed.

e3b94d4ef5 Bug #6737: REGEXP gives wrong result with case sensitive collation: 
- A new flag MY_CS_CSSORT was introduced for case sensitivity.
- Item_func_regexp doesn't substiture ICASE not only
  for binary collations but for case sensitive collations as well.

cbd3e61c8d Unicode collation algorithm: contraction support. 
E.g. 'Ch' is treated as a separate letter in Czech,
not as a combination of C+h.

c64d93b274 Allocate memory when a character set is requested: 
- For simple character sets: from_uni convertion table.
- For UCA: alternative weight arrays.

ebc3b3afac BTREE-indexes in HEAP tables can now be used to optimize ORDER BY 
Don't read character set files if we are using only the default charset. In most cases the user will not anymore get a warning about missing character set files
Compare strings with space extend instead of space strip. Now the following comparisons holds:  "a" == "a " and "a\t" < "a". (Bug #3152).
Note: Because of the above fix, one has to do a REPAIR on any table that has an ascii character < 32 last in a CHAR/VARCHAR/TEXT columns.

e0a0790ebb Fixed that multibyte charsets didn't honor multibyte 
sequence boundaries in functions LIKE and LOCATE in
the case of "binary" collation. Comparison was done
like if the strings were just a binary strings without
character set assumption.
