MySQL is set as UTF-8(utf8_general_ci: MySQL, Table, Column).
I can SELECT varchar value as original double byte character via ADODB and ASP(Legacy VB Script). These characters are inserted from phpMyAdmin.

ASP pages are saved as encoding Shift_JIS and ADODB connection parameter is indicated as dsn=…;APP=ASP Script;STMT=SET CHARACTER SET SJIS;

But when I will UPDATE field from ASP, updated varchar string has NO(ommited) double byte character but has single byte character in phpMyAdmin.

How to fix these update/insert issue?
I tried to change MySQL charset to sjis but it wouldn’t fix the issue.

    I could resolve the issue.
    Route cause is in SQL.

    UPDATE users SET name = N‘aaaa’ WHERE id = N’BBB’;

    This ‘N’ makes characters boroken.
    I was using ASP program with MS-SQL Server english version and this ‘N’ must be attached.
    I must remove all these ‘N’s when move to MySQL from MS-SQL!
