yes i have understood that there is no data of my problem. I'm telling you how to fix "encoding error" problem.
1. i edit to config.php after <?phpDEFINE('NOZIP', 1); and save it but not fix my problem.
2. i run some code in phpmyadmin sql
UPDATE setting SET value = '0' WHERE varname = 'gzipoutput';

UPDATE datastore SET data=REPLACE(data,'s:10:"gzipoutput";i:1;','s:10:" gzipoutput";i:0;') WHERE title='options';

And Disable to gzipoutput after entering to this code my encoding error problem was fixed.
