If file name have cyrilic letters,join function is not joining them.
Actually file size will be same with total other files but there is only one page
Example
So what i did ,i joined 3 file (1ы,2ы,3ы their total size is 80.5KB (all have one page inside these pdfs)) i got the file 1ы-joined (80 KB) but its joined only from the file 3ы.
How can i solve this?(i dont want to change letter to latin there is tons of files)
