dcc_detect_encoding

Reads up to <code>n_bytes</code> from the file and detects the most likely
character encoding via <code><a href="/link/stringi%3A%3Astri_enc_detect()?package=DCC&version=1.2.1" data-mini-rdoc="DCC::stringi::stri_enc_detect()">stringi::stri_enc_detect()</a></code>. Detected
encodings are normalized to the canonical names DCC supports as
first-class: <code>"UTF-8"</code>, <code>"GB18030"</code> (covers GBK/GB2312),
<code>"BIG5"</code>, and <code>"latin1"</code> (covers ISO-8859-1/windows-1252).

Rule-driven, auditable cleaning of survey and assessment
response data, implementing the WeianData Detect-Execute-Report
workflow. Provides a multi-format, multi-encoding input layer
(CSV, 'Excel', 'SPSS', 'Stata', 'SAS', Parquet, JSON), the
dcc_data container with a provenance chain, level-0 structural
diagnostics, five built-in response-quality detectors (missing
items, straight-lining, response time, trap items, score
anomalies), a declarative YAML rule engine, an execution engine
with a cell-level audit log, answer-key scoring, multi-form to
master item bank mapping, a normalized report model rendered as bilingual
staff workbooks and HTML, complete statistical bundles, and versioned
machine JSON/JSONL with findings-to-changes reconciliation,
cell-level lineage tracing, and
manifest-based one-command reproduction. Includes a protected bilingual
strict project workbook and matching JSON contract with cell-addressed
validation, non-mutating preflight, preview-first execution, and localized
staff guidance. All formally supported input backends install with the
package; PDF is optional rather than a fixed report output.
