Updated to the latest version of the plugin. The interface Russian is set to Russian.
If the attachment name is English and number, everything works fine.
If the attachment name is Chinese or Russian, the attachment name does not display Chinese or Russian after the attachment is uploaded.
(The old plug-ins 3-5 months ago do not have this BUG.)
Original attachment name:561–1—Вся работа- М11 23.05.18 — 加括.docx
Name after upload :561–1—-1123-05-18-.docx
