I'm having font problems, or maybe character encoding on wordpress.
I am building a Thai website, most of the articles are in the correct language and there is no problem.
But there are a number of articles posted when posting errors in the article letters.
https://prnt.sc/vswh8j or https://prnt.sc/vswi15
As in the picture I have given, some of the first characters can be Thai, but the following characters are like: "à¸µà¹ˆà¹ € à¸ £ à¹ ‡ à¸§à¸" and I don't translate get it in any language.
I don't think my source code supports Thai or something like that. I have tried researching on this problem a lot and tried many ways but to no avail.
Hope you can guide me to fix it. Thank you very much
