📝 Walkthrough

Walkthrough

ReportWriter now writes reports with explicit UTF-8 encoding in both atomic write paths. A test verifies UTF-8 bytes for non-ASCII report content.

Both atomic write paths use StandardCharsets.UTF_8. The test verifies the UTF-8 bytes for non-ASCII content.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: ⚪ Minimal · up to debc0

Reports now consistently use UTF-8 rather than the host default charset, preserving non-ASCII content across environments. Both write paths are updated and covered by a byte-level UTF-8 test, with no remaining merge-blocking risk.

Add non-ASCII regression coverage.

The existing report/src/test/java/org/hjug/refactorfirst/report/ReportWriterTest.java:146-158 test writes ASCII content only. It passes with both UTF-8 and the platform default charset. Add content such as café 漢字 😀 and compare the file bytes with content.getBytes(StandardCharsets.UTF_8). Exercise both writer implementations when the test setup permits it.

Also applies to: 221-221
