/* The layout of the data is as follows:
*
* The first part of the data contains rows of length max_seq_len + 1,
* where the first element is the item of the sequence, and the
* following elements are offsets to the data for sequences that
* start with the first item of length 2, ..., max_seq_len.
*
* The second part of the data contains the rest of the sequence
* data. It does not have a fixed stride. For each sequence, we
* put seq[2], ..., seq[len - 1], followed by the encoded value
* for this sequence.
*
* The values are encoded as follows:
*
* If the value is a single Unicode character smaller than 0x8000,
* then we place it directly. Otherwise, we put the UTF8-encoded
* value in the char_data array, and use offset | 0x8000 as the
* encoded value.
