-stdout unreadable output

Hi

When I use below code to test the output the output words are unreadable please check the picture 

hashcat.exe -m 2500 -S test.hccapx word-list.txt --session=test --status -r Test.rule --stdout -o output1.txt

is there any problem with my code or from the windows itself
I'm using version 6.2.1 on Win 10
