This is a list of issues with Unicode Technical Report #50. It exists because afaict Unicode doesn't issues in public (if at all?).

- Small forms parens Tr vs R
- Ideographic space U+3000 SVO=MVO⇒U
- Brackets U+2329, U+232A MVO⇒U
- overlines and low lines and DOUBLE LOW LINE (SVO)
- Musical symbols Cf should be R, not U, since they're connectors
