Download File Encoding Checker 3.15.1

EncodingChecker v3.15.1
One reporting fix: a preview no longer calls files Converted. What EC detects, converts
and refuses is unchanged.

A preview says WouldConvert
-WhatIf, -Plan, and the GUI’s preview followed by Export all results as CSV…
wrote Converted in the CSV Result column for each file a real run would convert,
although nothing was written. On the command line, only the journal marked the run as a
preview. The -Verbose breakdown counted those files as Converted too.
A file that a preview only decided to convert is now WouldConvert, in the CSV (on
stdout, written with -Report, or exported from the GUI) and in the -Verbose
breakdown. Converted appears only for a file EC wrote. A file the run never reached
still reads NotAttempted. The reverse does not hold: an Error row may still have been
replaced, which the journal records.

Compatibility
The CSV Result column has a new value. A script that counted Converted rows in a
preview or a -Plan run to learn what would change must now match WouldConvert, and a
script that checks for a fixed set of Result values will meet a new one. Rows from a
real run are unchanged.
The journal, the exit codes, conversion semantics (8), the plan schema (6) and the
journal schema (6) are unchanged. Plans written by v3.15.0 still apply.

Verification
- 987 tests pass, none skipped; release build with no warnings.
- docs/Test-DefectBacklog.ps1 passes: 87 findings, 76 fixed, 7 open.
- The Shared Unicode detector parity check is unaffected: neither shared detector
file changed.
- The four-corpus audit was not run. It applies to detection and conversion-policy
changes, and this release changes only how a preview is reported.
- The executables are not code-signed. The signing secrets are not configured, so
the release workflow skips signing. Shipping unsigned is a decision for this release,
not a passed check.

Known open issues
Recorded in DEFECT-BACKLOG.md: a file name with an unpaired UTF-16 surrogate cannot be
planned or backed up (BL-43); it never changes a file’s bytes.
