When a file is uploaded (for example, an Image) Flysystem strips unprintable characters from the file, which later leads to the wrong URL being generated for file access, resulting in a 404 error.

Steps to reproduce:
1. Clean installation of eZ Platform v2.5/Ibexa DXP v3
2. Prepare a JPG file named (select whole string, copy and paste it):

te­st.jpg 

containing "soft hypen" character.
3. In the back-office, create a new Image containing a previously prepared JPG file.

Result:
The newly created Content image will point to a nonexisting file (404 error).

Expected result:
The newly created Content image is displayed normaly.

Note:
This issue has to be also checked against the legacy installation and upgrade process, as in the legacy the issue wasn't present.
