Question Why Kunena 4.x allows utf-8 characters in attachment filenames?

Today I tested with Kunena 5.0 RC4,which is the latest version. It still allows UTF-8 characters in attachments filenames !

There IS NOT any option in Kunena configuration to prevent this!

When will you implement this feature? In the final Kunena 5 stable?

its on our list for next rc.

OK. Thank you. I am looking forward to test that version.

If we introduce an option like that in Kunena 5.0, your files already uploaded keep the utf8 characters in the filename so the issue will still happen

I'am thinking to add a tools instead an option to remove all utf8 characters in filename, think it will be better

I suggested "validation and reject" because it is more easier to implement. I don't want to put more work on your shoulders.

If you are willing to go further to handle both "formerly uploaded files" and "files will be uploaded later on", that will be great!

Thank you.

Today I tested with Kunena 5 RC5, on the attachment filename issue. Is seems that you had implemented some method in this version to "automatically convert the UTF-8 filename".

However, I also noticed that, the new method of conversion not only changed the "filename" part, but also changed the "extension name" part.

For example, I uploaded a file named in Chinese:

Kunena 帖子中站内链接 nofollow 问题.txt

Then I checked the file system via FTP, I found a new file in /media/kunena/attachments/62 folder, the filename is:

2996962656838a97af4c5f926fe6f1b0

Look, there is no ".txt" part in this new filename. So you will never recoganize it as TXT file if you check the file system via FTP, or a file manager in your web Control Panel, or the SSH terminal.

Why just keep the extension name there, make the filename as:

2996962656838a97af4c5f926fe6f1b0.txt

I think the latter is better.

Thank you.

do you have enabled protected uploads? when you disabled you get: Kunenanofollow.txt

I got Kunenanofollow.txt on your txt file

Yes, I had enabled "Protect Attachment". When disabled, the file extension name was kept.

Thank you.

protected hides also the extension name, so nobody can steal the attachment
