Hi, from what I understand Freetype has vertical glyph metrics that properly denote how to display vertical text for languages such as Japanese, Chinese, etc. It would be great to have vertical text in TextMeshPro as this would add so much more proper rendering of cultural narratives, etc.
The inability to support vertical text and only horizontal text loses a big amount of expression that’s possible, and I personally don’t feel it should be too difficult a feature to implement.
This is also a feature that Unreal is still lacking on, thus would act as incentive to use Unity.
