Does php fail to recognize files with Chinese names (the character set is the file system of utf8)

The file under Linux is saved with a Chinese name. How to read a save into a new single byte name. When php has the same name, an error occurs. The file does not exist. The Linux system is encoded in utf8. Is php unable to recognize files with Chinese names (the character set is a file system with utf8)?
