[Error] How to display Chinese or Japanese characters in the game?

[kouhumi]

I make an NPC event and use "Show Text" and type in some Chinese / Japanese characters, they become unreadable square bytes in the game.

I've tried:
1. install a Chinese font in the Fonts folder and change the FONT_NAME variable in MessageConfig.
result: The font is changed but still don't display Chinese characters.

2. follow the wiki translating the game.
result: I managed to choose the second language, but still don't display.

Any help is greatly appreciated!

I solve it indirectly by using a v.16.2 Pokemon Essentials, totally enough for my game.
After some digging into the script of 19.2, I found the basic function of drawing text is in MKXP_Compatibility, draw_text(), it basically draws every text in the game.
In 16.2 version, it uses RGSS2, so I guess the problem lies in MKXP?
I didn't go deep in MKXP's source code, so if anyone else want to display non-English characters in the game, maybe it's useful to take a look at MKXP!
