Hello,

At https://www.zabbix.com/documentation/2.0/manual/config/items/item/key:

Parameter - quoted string

If the key parameter is a quoted string, any Unicode character is allowed, and included double quotes must be backslash escaped.

I think it should read:

Parameter - quoted string

If the key parameter is a quoted string, any Unicode character is allowed (if UnsafeUserParameters=1), and included double quotes must be backslash escaped.

or similar
