Got error: 'latin-1' codec can't encode characters in position 0-12: ordinal not in range(256)

Hi, I'm testing certsync and getting following decoding error:

[*] Collecting userlist, CA info and CRL on LDAP
[*] Found XX users in LDAP
[*] Loading CA certificate and private key from administrator.pfx
[*] Forging certificates for every users. This can take some time...
[*] PKINIT + UnPAC the hashes

It worth to mention that there are cyrillic users in AD. I was trying to look into different places and even patched asn1crypto/core.py with using utf-8 instead of latin-1. However it didn't help: exception gone, but result was [+] 0 users dumped.

P.S. It may be a problem of my lab since I'm not able to dump hash for single user (proper encoding). Feel free to ignore this issue so far
