Uploading images with accents in the filename is failing. gzoritchak demonstrated the issue by uploading a file named “écran.png”, which failed, but succeeded when renamed to “ecran.png”. This problem affects users with non-English filenames, such as default screen capture filenames on French Macs. Matthieu pointed out that the issue also occurs with spaces in the filename. codinghorror and codinghorror acknowledged the bug and assigned it to zogstrip or eviltrout to fix. A fix has been implemented by zogstrip and is available in this commit.
The first time the name of the file is “écran.png”. At the end of the upload the link is not updated. The file was uploaded (you can check in the original directory).
