Issue with shared link + ?dl/?raw when it contains specific characters in Filename

Hi!

I have an issue with shared links with specific characters in the filename when combined with ?dl or ?raw parameter. When I replace the filename part with the ID of the file, the shared link does work (but that isn't the url returned by the API)

--------
Example 

File Constitucion.pdf (without ó)
(Does work)
https://www.dropbox.com/s/6ooz5iat88eat9t/Constitucion.pdf?raw=1

File Constitución.pdf (contains a "ó")
(Does work)
https://www.dropbox.com/s/y2f68dzf8vje3uv/Constituci%C3%B3n.pdf (Link returned by API)

(Doesn't work -> redirected to dropbox.com) https://www.dropbox.com/s/y2f68dzf8vje3uv/Constituci%C3%B3n.pdf?raw=1
https://www.dropbox.com/s/y2f68dzf8vje3uv/Constitución.pdf?raw=1

(Does work)
https://www.dropbox.com/s/y2f68dzf8vje3uv/id:4tUAwPcrBX0AAAAAAAAzhQ?raw=1

-------
Is this a bug or is there a specific reason for this behavior? And would it be possible to get the shared url with file ID in return of the /get_shared_link_file call to prevent this from happening?

I appreciate if anyone can help me out with this issue.

Cheers!
