I imported many pdf files from Evernote whose names contain Hebrew characters, such as ח רבעוני - ביטוח חיים - סוף רבעון 3 - לשנת 2025.pdf

I have two very serious problems: (1) Zoho Notebook cannot open the pdf file;  (2) It cannot download the pdf file.  All those pdf files are basically dead.   I cannot continue with this product unless there's a solution to these issues.
