package width
elem is an entry of the width trie. The high byte is used to encode the type of the rune. The low byte is used to store the index to a mapping entry in the inverseData array.
type elem uint16

const (
	tagNeutral elem = iota << typeShift
	tagAmbiguous
	tagWide
	tagNarrow
	tagFullwidth
	tagHalfwidth
)

const (
	numTypeBits = 3
	typeShift   = 16 - numTypeBits
tagNeedsFold is true for all fullwidth and halfwidth runes except for the Won sign U+20A9.
	tagNeedsFold = 0x1000
The Korean Won sign is halfwidth, but SHOULD NOT be mapped to a wide variant.
	wonSign rune = 0x20A9
