Change WordPress Database from latin1 to utf8 Encoding

Hi,

THIS PROJECT IS FOR MYSQL DATABASE EXPERTS NOT FOR WP DEVELOPERS.

A few months ago I have changed my WordPress hosting and that host converts my WordPress database into latin1 while migration of my site. Now I have changed my host but due to latin1 few features (e.g. WordPress multisite) of WordPress are not working.

When I changed following line in wp-config
from
define('DB_CHARSET', 'latin1');
to
define('DB_CHARSET', 'utf8');

My whole text matter (Hindi and Marathi) getting messed up, can you please fix and cover my database smoothly. see the URL all Unicode text got messed up https://durgshb3.sg-host.com/shop/amsy-the-power-beyond-your-subconscious-mind-marathi/

Here is the WordPress manual https://codex.wordpress.org/Converting_Database_Character_Sets

Here is one more person who faced an issue like me https://www.edubuzz.org/david/wordpress/changing-early-wpmu-db-to-utf8/

First, you need to fix the issue on the staging site and then you can work on the live site, we cannot do experiments on the live site, please note "datawowfix" in your bid so that I can understand you are bidding after reading the complete description
