日语模式下把 - 让给长音符（ー）输入，同时禁掉 -/= 的候选翻页： - 罗马字方案接受 VK_OEM_MINUS，set_raw_input 不再把 - 过滤掉； 罗马字表里本来就有 - 到 ー 的条目，只缺按键准入。 - n 后面接 - 时按辅音处理，让前面的 n 收成 ん，避免 n- 卡在 pending。 - 空编码时单独按 - 也起头组合，候选框第一项是 ー、第二项是普通 -。 - 组词流程同样适用：判据只看日语模式加组合状态，不再走翻页和词转字。 - -/= 在日语模式下不翻页，_ = + 这些没有假名写法的字符退回标点上屏， 并把 = _ 补进服务端的标点集合，和 TSF 侧保持一致，否则会等不到回包。 TSF 侧的影子分类、IsVirtualKeyNeed(ForFreshComposition) 和服务端按键策略 三处同时改，统一以配置项 input_mode == japanese 为判据（R 模式不在范围内， TSF 侧看不到临时会话，用会话类型判断会让两侧分类打架）。
Metasequoia IME for Windows
中文 README · Website · Docs · Privacy
A free and open-source Chinese and Japanese input method for Windows 10 and 11, built on TSF with no legacy IMM32 path.
This repository is the whole Windows product: the TSF text service DLL, the resident server, the conversion engine, a self-written native GUI framework, the HTML surfaces and the installer. The engine was imported from MSIME-Engine and specialized for Windows; it now lives in engine/ as a first-party component, so a plain clone builds the product. See engine/UPSTREAM.md.
This is a public beta. Expect rough edges and read the release notes before upgrading.
Install
Download the installer from Releases or the download page, run it, then switch with Win + Space.
Current builds are not code signed. SmartScreen will block them and uiAccess is unavailable, which means the candidate window cannot float above elevated applications. Verify the download with the SHA256 published on the download page.
You need the Microsoft Visual C++ 2015–2022 Redistributable (x64). The server and settings app are 64-bit; the x86 redistributable is a separate package and does not substitute for it. If you cannot switch to the IME, the server keeps exiting, or the settings window closes immediately, install that first.
What it does
- Chinese input: full pinyin, double pinyin (Xiaohe / Ziranma / Shoudao / Microsoft), Wubi 86
- Japanese input: romaji, with hiragana, katakana and dictionary candidates; also available as a temporary mode from Chinese
- Helpcode (形码) filtering on pinyin schemes: five tables, single- and double-code
- Optional cloud candidates, and AI suggestions via DeepSeek / OpenAI / SiliconFlow / Groq
- English-Chinese glosses in the vertical candidate window
- Mixed Chinese-English input, emoji and kaomoji, a dedicated English candidate mode
- Voice input with streaming recognition and optional cleanup
- Handwriting, on-screen keyboard, floating toolbar, clipboard history
- User dictionary management, candidate frequency tuning, skins with light and dark variants
Privacy
An input method sees every keystroke, so the boundaries are stated explicitly in PRIVACY.md: which features reach the network, what each one sends, what the defaults are, and how to turn each off.
Two things worth knowing up front. Cloud candidates are on by default — the composition spelling goes to Google's input-tools service, and it is the only network feature that works without you supplying a credential. API tokens are stored in plain text in config.toml, unlike macOS and Linux which use the Keychain and Secret Service.
There is no telemetry, analytics or crash reporting of any kind.
Building and contributing
CONTRIBUTING.md has the environment, the build order and what to run before opening a pull request. Contributions do not have to be code — dictionary entries, documentation, icons and compatibility testing all count, and the recruiting page lists them by area.
Note that most issues, documentation and code comments are in Chinese. English pull requests and issues are welcome.
