utf-8 problem?

[Nounou]

Hi,

I've got a problem with some passwords. I do my tests with Korelogic 2015's NT street hashes.

Let's consider one of them. ocl/hashcat can crack it and give me a password like $HEX[hex(password)].
I convert the hex(password) into a utf-8 string and write it into a "UTF-8 Unicode text" file.

Unfortunately, I am not able to crack my hash with -a 0 attack with this file.
JTR is able to find the password with the same dic file. 

Can you help me please ?

This is a known error, but it occurs only in the NTLM hashes
