Great Project.
The font issue has bothered me for days.

TL;DR
1. Simplified Chinese Font Tofu
2. openrct2 --verbose > openrct2.log 

OpenRCT2, v0.3.3-49 (0a47d2157 on develop)
Linux (arm)

3. I've installed the suggest font MS YaHei 

fc-list | grep 'YaHei'

4. As in 'fc-list', '微软雅黑' is the Chinese font name of 'Microsoft YaHei'

Before I delve down the rabbit hole of fontconfig, I'm seeking a quick solution here.
Thanks.

Full process,

1. I'm using the latest git source, OpenRCT2, v0.3.3-49 (0a47d2157 on develop)

2. TwisterOS, Debian based, Raspberry Pi 4B 

uname -a

4. make log

pls check the attached file openrct2make.log

some warnings of type of symbol when linking, not sure it's harmful or not.

e.g. 

/usr/bin/ld: warning: size of symbol `glGetIntegerv' changed from 44 in CMakeFiles/openrct2.dir/src/openrct2-ui/drawing/engines/opengl/OpenGLAPI.cpp.o (symbol from plugin) to 4 in /tmp/ccN450ia.ltrans23.ltrans.o
/usr/bin/ld: warning: type of symbol `glGetIntegerv' changed from 2 to 1 in /tmp/ccN450ia.ltrans23.ltrans.o

5. English Language is fine, while CJK all tofu.

Drawing Engine is Software as suggested in other post when using CJK.

pls check the uploaded images en-us.png and zh-cn.png

 

6. I've also tried Micro Hei via package 'apt install fonts-wqy-microhei' , but no luck. 

fonts-wqy-microhei/stable,now 0.2.0-beta-3 all
  Sans-serif style CJK font derived from Droid

fc-list | grep 'Micro Hei' 

/usr/share/fonts/truetype/wqy/wqy-microhei.ttc: 文泉驿微米黑,文泉驛微米黑,WenQuanYi Micro Hei:style=Regular
/usr/share/fonts/truetype/wqy/wqy-microhei.ttc: 文泉驿等宽微米黑,文泉驛等寬微米黑,WenQuanYi Micro Hei Mono:style=Regular

7. Below is the conf of WQY Micro Hei, for you to pin down the issue.

cat /etc/fonts/conf.d/65-wqy-microhei.conf

I've read all that I find from forum post and github issue related to font tofu. 

Maybe the reason is that fontconfig recognized the font using it's Chinese Font Name while OpenRCT tries English Font Name?

If so, how to solve this?

There's a work-around in github issue area. 

https://github.com/OpenRCT2/OpenRCT2/issues/13232

https://github.com/keithstellyes/OpenRCT2/commit/3fd43545d00ba4cf0f1bf9bab8092353de397db7

After modifying src/openrct2/platform/Linux.cpp according to keithstellyes' commit and re-compile,

openrct2 starts listening to fontconfig and no tofu this time.

I'm not sure this is the right approach. However this is a bit too difficult for common users.

And it doesn't exlain that I've installed the right font file but fontconfig register it by Chinese font name while openrct2 cann't use it.

Thanks,  keithstellyes.

If anyone got ideas about solving the fontconfig issue, pls help :)

And I'm now in the fontconfig rabbit hole ...
