What 愾 means
It means a long sigh, or literary anger and resentment.
You meet it in the Shijing's Xia Quan: 愾我寤歎,念彼周京 — waking with a sigh, longing for Zhou's capital. That is political grief, not a texted sigh. Built around 氣 for sound, it later leans toward anger and shared hostility in fixed compounds, close to 慨 and 喟.
Literary and rare alone; clearest for anger inside fixed compounds.
Is 愾 safe to send alone? Usually no: add surrounding words if you mean anger.

1Why does 愾 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
