I wouldn't be surprised though it does validate online (unless copy-paste in chrome automatically changes the encoding!) I'm using the prometheus-cpp library and I cannot find any mention of character support. Does Prometheus not have any way to convert incoming data? The strings I am using as labels come from very old code which is quite fragile, so fixing it outside our code would be far preferable - other code may rely on it being in whatever encoding it is in.
