How to render foreign characters on webpage

Question

Problem: I am not able to display characters correctly in Japanese, Chinese, Russian and so forth on the webpage. I am able to get some characters to display correctly in the Spanish version. However, for other languages, it breaks. I am not sure how to approach this. I am also using Mura CMS for the website and was not able to find a way to render the characters through their.

I am seeing the following on the webpage.
