URL 中带有百分比的文件名

Question

I have a directory that contains several pdfs, I have a script that sets the path for access and everything else,

<a href="<?= get_home_url().'/'.$certificate->file_path.'/'.$certificate->file_name ?>" target="_blank">Baixar</a>

however I am having a 404 error in files that contain accents of type (comma and percent),

File with accent:

http://exodocientifica.com.br//_fispq/ALARANJADO%20DE%20METILA%200,2%.pdf

other files without accent are normally accessed,

File without accent: http://exodocientifica.com.br//_fispq/ALARANJADO%20DE%20METILA.pdf

already I tried using functions like urlencode, htmlentities, hand did not get results

Answer 1

You should encode % with %25 since it is a special character in URL. Try using this URL instead:

http://exodocientifica.com.br//_fispq/ALARANJADO%20DE%20METILA%200,2%25.pdf
