How can I fix this?

Can you give me your pdf file name?

I will test what's wrong.

Thanks report!

@manateelazycat All my pdf files will report the errors.

[manateelazycat]

@FirstLoveLife I know, i mean can you give me your pdf, let me test it ?

[FirstLoveLife]

Sure: https://www.cs.cmu.edu/~410/self.pdf
I use eaf to open this file originally.

[manateelazycat]

@FirstLoveLife I have test, works fine for me.

You can try below method:

1. Start emacs with command "emacs -Q", then load eaf test again.

If Emacs -Q works fine, it's must be something wrong in your Emacs config.

2. M-x ielm RET
   Execute (setenv "LANG" "en_US.UTF-8") in ielm, then test again.
   If setenv can work, you need set your system LANG env to make support unicode filename

Thanks! I even forgot to use -Q. MY BAD!
