This allows us to skip and speed up some very common character converts that MySQL is doing when sending data to the client and this gives us a nice speed increase for most queries that uses only characters in the range 0x00-0x7f. This code is based on Alexander Barkov's code that he has done in MySQL 6.0 include/m_ctype.h: Added MY_CS_NONASCII marker libmysqld/lib_sql.cc: Added function net_store_data(...) that takes to and from CHARSET_INFO * as arguments mysys/charset.c: Mark character sets with MY_CS_NONASCII scripts/mysql_install_db.sh: Fixed messages to refer to MariaDB instead of MySQL sql/protocol.cc: Added function net_store_data(...) that takes to and from CHARSET_INFO * as arguments sql/protocol.h: Added function net_store_data(...) that takes to and from CHARSET_INFO * as arguments sql/sql_string.cc: Quicker copy of strings with no characters above 0x7f strings/conf_to_src.c: Added printing of MY_CS_NONASCII strings/ctype-extra.c: Mark incompatible character sets with MY_CS_NONASCII Removed duplicated character set geostd strings/ctype-sjis.c: Mark incompatible character sets with MY_CS_NONASCII strings/ctype-uca.c: Mark incompatible character sets with MY_CS_NONASCII strings/ctype-ucs2.c: Mark incompatible character sets with MY_CS_NONASCII strings/ctype-utf8.c: Mark incompatible character sets with MY_CS_NONASCII strings/ctype.c: Added function to check if character set is compatible with latin1 in ranges 0x00-0x7f
