**Issue Evaluation** Category: `bug` | Status: **Confirmed** The reported issue has been verified against the current codebase. **Root Cause:** `downloadCsv` in `web/src/utils/download.ts` creates a Blob with `text/csv;charset=utf-8` but does not prepend the UTF-8 BOM (`\uFEFF`). Excel and other encoding-sniffing applications fall back to ANSI/GBK when no BOM is present, causing all non-ASCII cells (Chinese topic names, alert labels, etc.) to render as mojibake. **Impact:** All CSV exports (topic, consumer group, DLQ, client connections, metrics, topic-comparison, user exports) produce unreadable files in Excel when the UI contains non-ASCII text. **Severity:** Medium — data is not lost, but exports are unusable for non-English users without manual re-encoding. **Note:** The server-side exporters (`AuditService`, `CloudCredentialService`) already handle this correctly with `\uFEFF` prefix. The fix is a one-line addition to the frontend `downloadCsv` function. PR #4743 from the author addresses this. Maintainers may proceed with reviewing that PR directly. --- *Automated evaluation by github-manager-bot* -- This is an automated message from the Apache Git Service.
