Khmer NIDA Keyboard is an input method (IME) app for HarmonyOS that supports sixteen languages in one keyboard: Khmer, English, Thai, Lao, Vietnamese, Chinese, Japanese, Korean, Myanmar, Arabic, French, Spanish, German, Portuguese, Indonesian and Malay.

Khmer input uses the official Microsoft KBDKNI NIDA keyboard layout — the same layout most Khmer typists already know.

Features:
- On-screen virtual keyboard with full NIDA layout (Base, Shift and Symbol layers)
- Sixteen languages, each using its own standard layout
- Accented Latin letters (é à ü ñ ß …): press and hold a letter on the on-screen keyboard, or use dead keys on a physical keyboard
- Full support for physical (USB/Bluetooth) keyboards, using each language's own standard layout
- Thai keyboard verified against the official Kedmanee (TIS 820-2538) standard
- Vietnamese Telex composing (type "aa" for â, "s" for the sắc tone, etc.)
- Chinese Pinyin input with a 49,506-entry dictionary and candidate selection
- Japanese input: romaji → kana, plus kana → kanji conversion with English meaning hints and a kana flick (かなフリック) 10-key layout
- Korean Hangul input (Dubeolsik) on both the on-screen and physical keyboard
- Live Translate mode: type in Chinese, Japanese or Korean and translate on the fly
- Word suggestions and autocorrect, including a personal dictionary you can edit or import/export
- Quick language switching: swipe the space bar or press Ctrl+Space on a physical keyboard
- Emoji panel organized by category, swipeable to browse quickly
- Built-in guided tutorial for first-time users
- Automatically adapts when a physical keyboard is connected or disconnected
- Dark and light themes with a choice of accent colors
- Adjustable keyboard height and full support for tablets and larger screens

This app is designed for anyone who needs accurate, standard multilingual text input on HarmonyOS phones, tablets and 2-in-1 devices — especially for Khmer, Thai, Lao, Vietnamese, Chinese, Japanese and Korean typists who want their own language's real standard layout, not an approximation.
