Can you try: curl host/metrics | promtool check metrics
Which will avoid any issues due to copying and means Prometheus sees the raw bytes. C++ std::string types (which is what prometheus-cpp uses: https://jupp0r.github.io/prometheus-cpp/structprometheus_1_1ClientMetric_1_1Label.html) don't have character set information associated with them, so it's likely you need to convert them yourself as the API doesn't have enough info to know what they are, e.g. using iconv() from ISO-8859-1 to UTF-8, which you then can put in a std::string.
