Hi, 

I'm getting this issue in my Zabbix but I couldn't find some way to troubleshoot this issue,

I attach the log that I'm getting anytime:

10955:20180518:074213.367 [Z3005] query failed: [0] PGRES_FATAL_ERROR:ERROR: invalid byte sequence for encoding "UTF8": 0xa1
[update items set error='Cannot create item: ¡Ÿ­Ì.

Best regards,
