When I tested the file preview today, I found that the text in the pdf was empty. When troubleshooting, I wanted to download the source file from the server. The following error was reported.
At first glance, I thought it was a permission problem. After checking the configuration, I found that it was the root user, so exclude ×
That is the problem of garbled characters in the file. After setting the encoding, there is no change. It is changed to a name that does not contain Chinese, and it is downloaded normally√
