The horizontalWriting value indicates that the writing direction is horizontal, either read left-to-right or right-to-left.

Some readers of languages that can be written horizontally or vertically have difficulty with one or the other writing direction. Setting this value allows the reader to determine if the text will be readable for them.

Only use the horizontalWriting value with languages that can be written in both horizontal and vertical directions (e.g., Japanese). Do not set this value for languages that are only written horizontally.

Use the verticalWriting value when the writing direction is vertical
