[FIX] web: NFD UTF-8 for safari in upload file

Before this commit, when uploading a file as attachment in Safari,
The file icon kept on showing 'downloading' whereas the request was successful

This was because the return from the server had a different UTF-8 norm than Safari

After this commit, it works well
