* fix(installer): 升级不再删除 custom_translations.txt custom_translations.txt 是用户手工放在数据目录根下的中英翻译覆盖表， 安装包不携带、引擎只读不写。覆盖安装时 CleanAppDataExceptUserFiles 会 清掉根下所有不在 IsPreservedAppDataItem 名单里的条目，换数据目录时 MigrateUserDataDir 的 robocopy 清单也不含它，于是升级会把它删掉，或留在 旧目录随 RemoveDataDir 一起消失。它没有 config.toml 那样的出厂副本可 回退，删掉即内容彻底丢失。 新增 IsUserTranslationFile 并接入 IsPreservedAppDataItem，覆盖安装时与 其他用户数据同等保留；MigrateUserDataDir 的 robocopy 文件清单补上它， 换数据目录时一并搬走。preserve-user-data.ps1 的 $required 同步更新。 同步 installer/README.md 的迁移清单与 PRIVACY.md 的升级保留说明，并订正 新增函数注释里引用的 README 章节名。 * fix(installer): 迁移 custom_translations.txt 时不覆盖、不静默丢失 换数据目录时 robocopy /MOVE 会用旧目录那份直接盖掉目标目录里已有的 custom_translations.txt，而冲突检查只管 config.toml。现在 ConfigMigrationProblem 对它做同样的检查：两份内容不同就拒绝这个目录，相同就删掉旧目录的残留再搬。 这也避免了 RemoveDataDir 在非独占目录里按名字删掉没搬走的那一份。 迁移失败时原先只有用户词库和 config.toml 会中止安装，custom_translations.txt 被当成皮肤一样可重建的东西只记日志。它没有出厂副本，新增 TranslationMigrationFailure，没搬成同样中止。 同步 PRIVACY.md 与 installer/README.md 的保留/迁移清单，补上此前就漏掉的 stats.db、helpcodes\custom、shuangpin、models。 --------- Co-authored-by: fanlusky <1730976608@qq.com>
Metasequoia IME for Windows
中文 README · Website · Docs · Privacy · Code signing policy
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 / Sogou / Ziguang / Zhineng ABC / Guobiao / Pinyin Jiajia), 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: six 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
- Local input statistics (off by default): character counts and active time stay on this machine; view and clean them under Settings → Statistics
- 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.
