The tables in this directory (single.bin, gb18030.bin, gb18030_ranges.bin,
big5.bin, big5_plane2.bin, jis0208.bin, jis0212.bin, euc_kr.bin and
labels.txt) are derived by regen.py from the index and label data of the
WHATWG Encoding Standard, https://encoding.spec.whatwg.org/ (indexes.json,
encodings.json; SOURCE records the exact files).

Changes: the indexes are stored as little-endian binary (16-bit code points,
Big5's plane 2 code points split into a bit table), and the labels as
"<encoding number> <label>" lines; no mapping is changed. tape's UTF-7
labels (labels.txt, encoding 41) are not part of the Standard.
