understand-commit_message_encoding_encoding_value

CALL NUMBER: deep_commit_object.commit_message_encoding_encoding_value DEFINITION: The character encoding name stored in the encoding header (UTF-8, ISO-8859-1, Windows-1252, etc.); controls byte-to-character interpretation of the message bytes.

Invoke this skill to understand commit_message_encoding_encoding_value down to its primitives. The RELATIVE ROOT below is the least-fixed-point closure of everything it bundles from — the full import cone, grouped by the lib each prim comes from. Projected from a prover-typed KB (MAP/SWI-Prolog consistency gate): every reference below resolves.

THE RELATIVE ROOT (the import cone, by lib)

from deep_commit_object

• commit_message_encoding_message_bytes (d1): Raw byte sequence forming the commit message body; decoded using encoding_value (or assumed UTF-8) to produce display characters.
• commit_message_encoding_original_encoding (d1): Alias for encoding_value; the encoding recorded at commit time distinguishing the message's original byte interpretation from the display encoding.
• commit_message_encoding_transcoding_logic (d1): git's internal conversion from the stored encoding_value to the requested log_encoding_flag encoding; uses iconv-style conversion with loss handling.
• commit_message_encoding_encoding_fallback (d2): Fallback behavior when transcoding_logic cannot map a character; typically replaces with a substitution character or skips the byte.
• commit_message_encoding_transcoded_message (d2): The output of transcoding_logic: message_bytes decoded then re-encoded into log_encoding_flag; git log emits this to the terminal.
• commit_message_encoding_display_encoding (d3): The terminal or output stream encoding git uses when writing the transcoded_message; git assumes UTF-8 output if terminal encoding is unset.
