CJK Input Bridge
by mituba4154
CJK Input Bridge connects Windows IME input to Minecraft text fields, so Japanese text can be typed with the candidate window shown next to the field.
What it does
Typing Japanese on Windows in Minecraft 1.12.2 relies on the operating system's input method editor, which Minecraft does not display properly by default. The mod passes the IME composition text into Minecraft text fields, shows the composition directly in the field, and places the candidate window near the current input position. Chat boxes, search fields and name fields are covered, as are configuration screens added by other mods.
The mod keeps the candidate window aligned when a long line causes the field to scroll horizontally, and it adjusts the window position under different GUI scale settings. IME input keeps working after switching tabs inside a GUI, and after leaving Minecraft with Alt+Tab. Committed text is passed on to some modded screens that use standard Minecraft text fields.
The mod is designed for Windows only, and macOS and Linux implementations are not included. Only Japanese input has been tested so far, and other input methods have not yet been confirmed, since results depend on the IME and system environment. Building the native part requires additional DLLs, CMake and the Visual Studio Build Tools.
Key features
Composition text in fields
IME composition text appears directly in Minecraft text fields during conversion, before the text is committed.
Candidate window placement
The candidate window opens near the current input location and stays aligned when long text scrolls within a field.
Scale-aware positioning
The window position is adjusted for different GUI scale settings, so it lands in the right place at each scale.
Input across tabs and focus changes
IME input continues working after switching tabs within a GUI or leaving the game with Alt+Tab.

What the author says
CJK Input Bridge is a mod that makes it easier to enter Japanese and other CJK text in Minecraft 1.12.2 on Windows. In Minecraft 1.12.2, text being composed with an IME may not appear correctly in the game, and the candidate window may be displayed far away from the text field.
