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

I remember that Kunena old versions will automatically rename filenames if there is any non-ASCII character in the attachment filename. But, recently, after I upgraded to Kunena 4.0.3, I noticed that it allows utf-8 characters in the attachment filenames. Why?

How can I configure Kunena to automatically strip non-ASCII characters from the filenames?

Thanks.

Hello,

You mean that it was the case with Kunena 3.0.8 ?

There is no setting to change that behaviour, i will check that if i can do something

Yes, when I was using Kunena 3.0.8, it will NOT allows non-ASCII characters in filenames of attachments. But after I upgrade to Kunena 4.0.3, and use still the Blue Eagle template (I don't like crypsis template because it has so many bad design), then I noticed that Kunena will keep the original filenames for attachments, without automatically change those non-ASCII characters.

This is very annoying. Because I always use Akeeba Backup to make site backups, but if the filename contains non-ASCII characters, then Akeeba Kickstart can NOT decompress the backup file. That means all backup files are cracked.

Hope you will fix this soon. and hope you will keep this feature for ever: never allow non-ASCII characters in filenames for attachments.

Thank you.

I have done a fix for it, you can try by applying changes here : github.com/Kunena/Kunena-Forum/pull/3355/files

I have uploaded your patch. Hope this will work.

Don't forget to "combine" this feature to Kunena for ever.

Thank you.
