PHP returns an error if the file name to be opened contains Chinese characters

I cannot use iconv.
$ File_read = "C:/China .txt ";

$ File_read = iconv ('utf-8', 'gb2312', $ file_read );

Report

------ Solution --------------------
What version of lz php? No error will be reported when I run your code in 5.2.
The error indicates that the string you want to convert contains invalid characters. Which of the following is escape?
------ Solution --------------------
Echo iconv ('utf-8', 'gb2312 // IGNORE ', $ file_read );

What is missing from the original string?
