Hi,
we encountered a problem with the exporter and utf-8 labels. When label value is not a valid utf-8 the prometheus client rejects it and exporter panics. We had invalid utf-8 value in the set name. This is certainly not a common issue but I think it is better to handle it if Aerospike server accepts it.
I will add this change also to this project https://github.com/aerospike/aerospike-prometheus-exporter/blob/master/watcher_sets.go after it will be merged here.
