Non-english characters in file names are stripped

[alperakgun]

Non english or accented characters in file names are replaced with underscore; for example; ça-über.xls is not allowed. This maybe a feature but maybe an option can be useful to switch to allowing international letter.. Kind regards

LINE 108:
instance_write(:file_name, uploaded_file['filename'].strip.gsub(/[^\w\d.-]+/, '_'))

This one works fine LINE 108
instance_write(:file_name, uploaded_file['filename'].strip.gsub(/[^\p{Word}\d.-]+/, '_'))
