I understand that metric and label *names* are standard ASCII but
*values* support
Unicode, at least according to docs.
I am working on a Swedish-language system and just realised several of my
targets are reporting this error, however their endpoints work just fine.
I have a metric with:
obfuscated_metric_name{location="Törn"} 0.00000000000000000
message_bytes_total{direction="sent",subsystem="ÖTPP"} 0.00000000000000000
I copy-pasted this from the endpoint apart from hiding the metric name for
privacy reasons so what is wrong? Our code is quite old C++ so quite how
these characters are handled is not obvious to me but we haven't had this
issue before (we use these strings all over the place) and when I paste
this text into a UTF8 validity checked, it reports no problems.
Does Prometheus have any configuration I can tweak otherwise I'm a bit
stuck!
Thanks for any help.
