Hi, I would like to ask if anyone has reported problems with filenames that contain different to English characters. In my case the problem is spotted when in K2 items I upload (attach) files with names that contain Greek characters. Then, once the K2 item is saved the filename is converted to something else. Does anyone know how to fix this?

Thank you in advance for any assistance!

Thanks for the reply. For example, when I upload the file "1aΑΝΑΚΟΙΝΩΣΗa1.pdf", which the filename contains greek, latin and numeric characters as depicted in Fig. 1, then once the K2 item is saved the filename is converted to "1aYYYYYYYYYYa1.pdf" (Fig.2). How I can preserve the original filename? I have already tried some suggestions with no luck, e.g. settig $this->file_auto_rename = false; from class.upload.php.

Thank you very much! Professional support as always!
