Your question is a bit unclear. X3 supports Chinese characters in folder names, at least on standard Apache servers with default PHP extensions. For example this website:
https://www.yuifu.com/
With Chinese folder name:
https://www.yuifu.com/品牌/
An image file inside a Chinese folder name:
https://www.yuifu.com/content/2.品牌/2.jpg
The only other issue with Chinese, is that sometimes you may need to select a FONT that supports Chinese characters, but that is not related to the system or ability to CREATE folders in Chinese. By default, it works fine in Chinese and any other east-asian language. If you have a specific problem on a specific platform combo, I would need login to check and test, for starters.
