Redmine

On Internet Explorer, a filename downloded from repository is broken, because that filename is consist of multibyte characters. But, that is absolutely normal on Chrome.
In addition, attached files in the Redmine "files" page have no problem.

I think that this code has no problem,

./controllers/attachments_controller.rb:
    send_file @attachment.diskfile, :filename => filename_for_content_disposition(@attachment.filename),

... and this code has a problem.

./controllers/repositories_controller.rb:
    send_data @content, :filename => @path.split('/').last

I test that modification like below, and it seems successful!

    send_data @content, :filename => filename_for_content_disposition(@path.split('/').last)

In my opinion, some of other

send_data
