[Prometheus supports this as of 3.0](https://prometheus.io/blog/2024/11/14/prometheus-3-0/#utf-8-support) but Mimir does not support it still. If UTF-8 is enabled, some tests will need work: - `TestLabelValuesCardinalityHandler_ParseError` - ... UTF-8 is specifically disabled in different places by setting `model.NameValidationScheme = model.LegacyValidation` in `init` functions.
