nvim（不使用 --embed 或 --headless）时，它会启动内置的“终端 UI”（TUI）。此默认 UI 是可选的：你可以将 Nvim 作为“无头”服务器运行，或者你可以使用 GUI。nvim 时，这将启动内置的 UI 客户端，该客户端会启动一个 nvim --embed 服务器（子）进程，UI 客户端将连接到该进程。在连接到服务器后，UI 客户端会调用 nvim_set_client_info()（如所有 UI dev-ui 所建议的那样）并在其通道上设置这些字段client = {
attributes = {
license = 'Apache 2',
pid = …,
website = 'https://neovim.fullstack.org.cn',
},
name = 'nvim-tui',
type = 'ui',
version = { … },
}Nvim 在启动时会猜测终端类型（除了 --embed 和 --headless 模式）。$TERM 环境变量是决定终端类型的主要提示。curl -LO https://invisible-island.net/datafiles/current/terminfo.src.gz gunzip terminfo.src.gz tic -x terminfo.src

CSI ? <flags> u这意味着你的终端支持“CSI u”编码，Nvim 将通过写入序列来告诉你的终端启用它
CSI > 1 u如果你的终端不支持“CSI u”，那么 Nvim 将改为通过写入序列来启用“modifyOtherKeys”编码
CSI > 4 ; 2 m当 Nvim 正常退出时，它会发送相应的序列来禁用特殊键编码。如果 Nvim 未正常退出，则你的终端模拟器可能处于错误状态。如果发生这种情况，只需运行“reset”。
