pub fn text_width(s: &str) -> usizeExpand description
The display width of s in terminal cells.
Measured per grapheme cluster, because that is the unit a surface advances
by: 👨👩👧 is five codepoints measuring 2 + 0 + 2 + 0 + 2 cells one at a
time, but the character they spell is drawn in 2. Both frontends already
measure it that way — ratatui asks unicode-width per cluster, and the GUI
asks its own text system — so the caret only lands where the text is if this
agrees with them.
