How to display Chinese characters in an English version of Windows PE.

Just out of curiosity...

I am running an English version of Windows 10 without a Chinese language pack. When I run "\sources\setup.exe" after mounting the following ISO, Chinese is displayed.

Win10_1903_V1_Chinese(Traditional)_x64.iso

If I am running an English version of Windows 10 PE and run the same "setup.exe", English will be displayed. Do you know why?

\sources\lang.ini and sources\zh-tw or \sources\zh-hk

The following is "\sources\lang.ini".

Code:

[Available UI Languages]
zh-tw = 3

[Fallback Languages]
zh-tw = en-us

Does it mean that en-us will be used if zh-tw cannot be used, as in an English version of Windows PE?
