In Vietnamese typography, the Acute (Dấu Sắc) and the Grave (Dấu Huyền) are mirror images. They must share the same form, weight, and angle.
The Acute signifies a rising tone, while the Grave signifies a falling tone.
Key Rule: Their bottoms should be narrower than their tops (like a droplet or a brush stroke), and they should be positioned symmetrically relative to the vertical axis of the letter.
Drag the Acute mark to its correct optical position. Aim for the "Safe Zone" above the x-height but slightly to the right of the center.
