A sustainable internationalization plugin for the DeepSeek Harness Web UI. Version 0.2.1 registers 20 locales from one registry while preserving DSH's existing client ModuleLoader integration, locale service, preference migration, and runtime fallback behavior.

Locales

繁體中文（香港、台灣）, 日本語, 한국어, Français, Deutsch, Español, Português (Brasil), Italiano, Русский, Українська, Polski, Nederlands, Türkçe, العربية, हिन्दी, Bahasa Indonesia, Tiếng Việt, ไทย, and Svenska.

• Traditional Chinese locales (zh-HK, zh-TW) fall back from the built-in Simplified Chinese dictionaries through the existing character converter.
• Arabic sets the document language and direction to ar / rtl; other managed locales use ltr.
• Untranslated non-Chinese values fall back to English.

Features

• Adds all 20 locales to Settings → General → Language, alongside the built-in 中文 / English.
• Per-language hand-polished translations for every official locale namespace (715 strings each), from an English baseline.
• Runtime fallback: new/updated/third-party strings fall back to English (or Simplified→Traditional conversion for zh-HK/zh-TW), so upstream UI updates and other plugins are covered without re-translating every language.
• Language preference persisted in browser localStorage; reload-proof.
• Auto-translate: with a non-Chinese locale active, long English text (plugin-market descriptions, third-party UI, error prose) is auto-translated to your language through your configured model, and cached so re-renders don't undo it. The default language (en/zh) is left untouched; Traditional Chinese keeps the built-in Simplified→Traditional conversion instead of calling a model.
• Zero intrusion on dictionaries: no upstream package changes, silent degradation if the locale service is missing.

Install

Install from npm (exact version — this is what DSH Desktop's Market update button needs):

dsh plugin --profile <active-profile> add @mimateinn/[email protected]

Or from GitHub, pinned to a commit:

dsh plugin --profile <active-profile> add github:mimateinn/dsh-i18n#<commit>

For DSH Desktop the active profile is the active value in %APPDATA%/DSH Desktop/profile-selection/state.json (usually desktop). The per-profile shim host-commands/<profile>/bin/dsh.cmd bakes its own profile name into the command, so running the web shim installs into the web profile even while Desktop is showing desktop — the install succeeds and the plugin is never loaded. Pass --profile explicitly to be sure.

DSH Desktop's Market install paths accept only an exact published npm version, so a GitHub spec must go through the built-in terminal dsh plugin add, which forwards the specifier to pnpm unvalidated.

Restart the host, then choose a language in Settings → General → Language. Remove with dsh plugin --profile <active-profile> remove dsh-i18n.
