“lsmod” has the advantage of listing dependencies. What do you see from “lsmod”?
Do you have your module located here?
/lib/modules/$(uname -r)/kernel/fs/nls/nls_utf8.ko
Also, here is a similar older thread you might want to use as a checklist:

As for “ls /Misc”, if this is a mount point, then it must exist before anything can mount to it. Prior to attempting the mount, does “ls /Misc” still say it does not exist? If not, then this is a problem, and you could create this via “sudo mkdir /Misc”.
