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. mysql-test/r/case.result: Update result file. mysql-test/r/compress.result: Update result file. mysql-test/r/ctype_collate.result: Update result file. mysql-test/r/date_formats.result: Update result file. mysql-test/r/ddl_i18n_koi8r.result: Update result file. mysql-test/r/ddl_i18n_utf8.result: Update result file. mysql-test/r/fulltext.result: Update result file. mysql-test/r/func_crypt.result: Update result file. mysql-test/r/func_encrypt.result: Update result file. mysql-test/r/func_if.result: Update result file. mysql-test/r/func_in.result: Update result file. mysql-test/r/func_like.result: Update result file. mysql-test/r/func_regexp.result: Update result file. mysql-test/r/func_set.result: Update result file. mysql-test/r/func_str.result: Update result file. mysql-test/r/func_time.result: Update result file. mysql-test/r/gis.result: Update result file. mysql-test/r/group_min_max.result: Update result file. mysql-test/r/mysqldump.result: Update result file. mysql-test/r/negation_elimination.result: Update result file. mysql-test/r/null.result: Update result file. mysql-test/r/select.result: Update result file. mysql-test/r/show_check.result: Update result file. mysql-test/r/sp-code.result: Update result file. mysql-test/r/ssl.result: Update result file. mysql-test/r/ssl_compress.result: Update result file. mysql-test/r/subselect.result: Update result file. mysql-test/r/temp_table.result: Update result file. mysql-test/r/type_blob.result: Update result file. mysql-test/r/view.result: Update result file. mysql-test/suite/binlog/r/binlog_stm_blackhole.result: Update result file. mysql-test/suite/rpl/r/rpl_get_lock.result: Update result file. mysql-test/suite/rpl/r/rpl_master_pos_wait.result: Update result file. mysql-test/t/view.test: Add a test case for Bug#32538. sql/item.cc: Do not dump character set introducer if it was not specified explicitly in the original query. sql/item.h: Add 'cs_specified' property to Item_string. sql/sql_yacc.yy: Set Item_string::cs_specified property to TRUE when character set introducer is explicitly specified.
