unicode-width features: what each one does, and the line to copy
Short answerunicode-width 0.2.2 has 3 features. By default it turns on cjk; add default-features = false to start from nothing. It needs Rust 1.66 or newer.

| Feature | In default | Turns on |

cjk | yes | nothing else (a switch the code checks) |
no_std | nothing else (a switch the code checks) | |
rustc-dep-of-std | std, core |
dep:x turns on the optional dependency x; x/y turns on feature y of dependency x (with ?, only if x is already on).
