Subject: 28.0.91; browse-url-of-dired-file fails with wrong type argument error
Date: Sun, 06 Mar 2022 08:54:27 -0300

Hi All,

I've been trying out the pre-release and met an issue with 
`browse-url-of-dired-file'.

Whenever I try to use it, I get the error "url-file: Wrong type 
argument: number-or-marker-p, nil".

As far as I can tell, the issue is not related with file/mime type. 
I've tried it with files I'd expect would be opened with an external 
application and with Emacs: .png, .jpg, .odt, but also .org, .tex. All 
with the same results.

However, as far as I can tell, the issue arises for file names with no 
ascii characters.  If the file name is well behaved, it works as 
expected.  But as soon as, e.g. an accented letter is part of it, the 
issue is triggered.

To reproduce, start with `emacs -Q'. Create a file named 
"~/test/áçãü.org", open `dired', and navigate to that file, and hit "W" 
(`browse-url-of-dired-file') on it.  You should get the mentioned error 
"url-file: Wrong type argument: number-or-marker-p, nil".

The backtrace is:

Since I use this functionality somewhat regularly, and hadn't met it 
with 27.2, as far as I can tell this is a regression since then.

Best regards,
Gustavo.
