# error.ControlModeErrorKind.UnrepresentableCommand

- **Module:** error.ControlModeErrorKind
- **Package:** libtmux
- **Language:** Rust
- **Kind:** constant
- **Source:** https://github.com/libtmux/libtmux-rs/blob/8a648c0894dfffc9303583f753b6c8ae01f2fe76/crates/libtmux/src/error.rs#L155
- **Page:** https://libtmux.org/reference/rs/error-controlmodeerrorkind-unrepresentablecommand/

The command contains an argument no control-mode line can carry.

Control mode is a text protocol, so an argument that is not UTF-8
cannot be sent over it even though the same command would run fine as
a subprocess.
