MDEV-33772 Bad SEPARATOR value in GROUP_CONCAT on character set conve…
…rsion Item_func_group_concat::print() did not take into account that Item_func_group_concat::separator can be of a different character set than the "String *str" (when the printing is being done to). Therefore, printing did not work correctly for: - non-ASCII separators when GROUP_CONCAT is done on 8bit data or multi-byte data with mbminlen==1. - all separators (even including simple ones like comma) when GROUP_CONCAT is done on ucs2/utf16/utf32 data (mbminlen>1). Because of this problem, VIEW definitions did not print correctly to their FRM files. This later led to a wrong SELECT and SHOW CREATE output. Fix: - Adding new String methods: bool append_for_single_quote_using_mb_wc(const char *str, size_t length, CHARSET_INFO *cs); bool append_for_single_quote_opt_convert(const char *str, size_t length, CHARSET_INFO *cs) which perform both escaping and character set conversion at the same time. - Adding a new String method escaped_wc_for_single_quote(), to reuse the code between the old and the new methods. - Fixing Item_func_group_concat::print() to use the new method append_for_single_quote_opt_convert().
