Defect #27076

Cannot open attachements with special characters in filename
Added by Markus Schenk about 7 years ago.
Updated about 7 years ago.
Description
When an attachment is added to a new entry with a special character in the filename, it is not possible to open the attachment after saving (404 - document not found).
After some investigating I found that the attachment in the database uses two columns to determine the matching between displayname and actual file on disk - 'filename' and 'disk_filename'.
An attachment with a special character in the filename (eg. täst.txt) is saved in the database like that: 'filename' => 'täst.txt', 'disk_filename' => '170926091327_3de45324.....txt'.
In redmine, the attachment name is shown as täst.txt but the underlying href link points to t%C3%C4st.txt and on open leads - as mentioned before - to an error 404.
Now, when I update the corresponding database entry to 'filename' => 't%C3%C4st.txt' the link then works. Unfortunately redmine then displays the name as 't%C3%A4st.txt'.

Well, before updating I checked the redmine install wiki page for a recommended version. The recommended version is 4.2 so I used the most current 4.2. release.
Thank you for the fast response. I will downgrade my rails version.
Redmine uses pinned Rails version in order to prevent behaviour change link this issue.
source:tags/3.4.2/Gemfile#L7
How do you use Rails 4.2.9?
