Logs?

so i've been trying to access the files to my minecraft realms logs though my files but everytime i try and see what text is inside the logs files it either tells me im not using the right launcher or when i do manage to open it in a .txt file all it does is give me this weird text shown below,
ܕᜁᘒရ␣ᄂԬ∝ؘ̈:white_large_square:㈭㔴ฏ⼪┮㌦
i'm not sure what this means or if this is a bug with my logs files or not and is there any way i can fix this issue?
