I am trying to show Thai Characters in my app PHP / MySQL, data is being inserted from a backend process to the database and Thai chars are in the Database, but are not show in the front end. PHP.
I have tried with UTF-8 encoding in the page, and Windows-874
What is the right combination for this to be shown correct in the Browser?

The site where you enter the text need to be utf-8 encoded and the table field.
Another thing which is often forgotten is to set
after opening the connection.
(And, of course, the frontend must be utf-8 encoded.)
