-// The mapping from rune to string (i.e. offset and length in the data string)
-// is encoded as a two level table. The first level maps from contiguous rune
-// ranges [runeOffset, runeOffset+runeLength) to entries. Entries are either
-// direct (for repeated names such as "<CJK Ideograph>") or indirect (for runs
-// of unique names such as "SPACE", "EXCLAMATION MARK", "QUOTATION MARK", ...).
-//
-// Each first level table element is 64 bits. The runeOffset (21 bits) and
-// runeLength (16 bits) take the 37 high bits. The entry takes the 27 low bits,
-// with directness encoded in the least significant bit.
-//
-// A direct entry encodes a dataOffset (18 bits) and dataLength (8 bits) in the
-// data string. 18 bits is too short to encode the entire data string's length,
-// but the data string's contents are arranged so that all of the few direct
-// entries' offsets come before all of the many indirect entries' offsets.
-//
-// An indirect entry encodes a dataBase (10 bits) and a table1Offset (16 bits).
-// The table1Offset is the start of a range in the second level table. The
-// length of that range is the same as the runeLength.
-//
-// Each second level table element is 16 bits, an index into data, relative to
-// a bias equal to (dataBase << dataBaseUnit). That (bias + index) is the
-// (dataOffset + dataLength) in the data string. The dataOffset is implied by
-// the previous table element (with the same implicit bias).
