TXT translation test files (BookTranslator, 2026-10-28). Free to reuse.

source-unwrapped.txt         396-word English story written for this test: 3 chapter headings,
                             15 paragraphs, dialogue, a 5-line letter whose line breaks matter,
                             and a "* * *" scene break. One paragraph per line.
source-wrapped.txt           the same words, hard-wrapped at 66 characters (the letter, headings,
                             and scene break keep their own lines). 57 lines, 43 of them non-empty.
sample-zh-gb18030.txt        short Simplified Chinese sample saved as GB18030
sample-zh-utf8-bom.txt       the same text saved as UTF-8 with a byte order mark
sample-ja-shift_jis.txt      short Japanese sample saved as Shift_JIS (Python codec cp932)
sample-en-utf16le-bom.txt    English sample saved as UTF-16 little-endian with a BOM, CRLF endings
check_txt.py                 inspect / convert / compare (Python standard library only)
check-results.txt            checker output for every sample and every translation
run_llm_txt_test.py          runs the three conditions against a local OpenAI-compatible server
outputs/*.txt                the nine Simplified Chinese outputs, unedited
results.csv                  one row per run, including the readings the checker cannot do

Conditions:
  wrapped     the whole hard-wrapped file in one request
  unwrapped   the whole unwrapped file in one request
  chunked     the hard-wrapped file cut every 12 lines, one request per chunk, replies joined
              with a newline (this imitates a splitter that counts lines, not paragraphs)

Model: Qwen 3.6 27B (qwen/qwen3.6-27b, Q4_K_M) in LM Studio, reasoning_effort "none",
temperature 0.3, the same one-sentence prompt for every request, Apple M4 Max with 64 GB of
memory. Three runs per condition, nine in total, on October 28, 2026.

The wrong-actor and "learned at a convent school" columns were read by a person: the English
says the ticket-booth man pointed at the building and went back to his crossword, and that the
grandmother learned her handwriting at a convent school.
