Bug: need support for other lang

[ttxs25830]

Failed to check if the command is success when system is set to use other languages. For example, in Linux we use this code to disconnect WiFi:

/// Attempts to disconnect from a wireless network currently connected to.
    fn disconnect(&self) -> Result<bool, WifiConnectionError> {
        let output = Command::new("nmcli")
            .args(&["d", "disconnect", "ifname", &self.interface])
            .output()
            .map_err(|err| WifiConnectionError::FailedToDisconnect(format!("{}", err)))?;

        Ok(String::from_utf8_lossy(&output.stdout)
            .as_ref()
            .contains("disconnect"))
    }

But when locale is set to other language, this command's output is look like this: 成功断开设备 "wlan0"(For LANG=zh_CN.UTF-8) As result, this command always returns Ok(false) even if it did disconnect the WiFi.

Thanks for raising this issue @ttxs25830. I never considered that case, and apologies for that.

If you'll like to work on a fix that'll be awesome; we can have a discussion on how to approach it so that it can also extend to other languages.

Else, I'll try to circle back to it when I've got some free time.
