## Summary Closes #7010. Use UTF-8 explicitly for Basic credentials in both the data-source connection probe and the actual Prometheus-compatible range query. The previous Spring default is ISO-8859-1: it silently changes Latin-1 credential bytes and throws for Chinese/emoji credentials. ASCII headers remain byte-for-byte equivalent. This matches [Prometheus's documented UTF-8 password hashing](https://prometheus.io/docs/guides/basic-auth/#hashing-a-password) and [its authentication handler's comparison of the received password bytes](https://github.com/prometheus/exporter-toolkit/blob/v0.14.1/web/handler.go#L98-L119). ## Validation - Before: all 6 new cases fail, covering accented Latin characters, Chinese, and emoji in both request paths. The range fixture returns HTTP 401 for the wrong Basic header; unencodable credentials fail before sending. - After: `mvn -B -ntp -Dtest=PrometheusMetricsSourceTest,SettingsServiceTest test`: 77 tests pass on Java 21; Checkstyle passes. - The range-query cases exercise a local HTTP server and the connection-probe cases assert the exact request header. Existing ASCII and Bearer cases also pass. - `git diff --check` passes. - No external Prometheus deployment or full backend suite was run locally. AI assistance was used; the diff and before/after regression results were reviewed. -- This is an automated message from the Apache Git Service.
