1. Overview
Unicode characters can be entered and edited using several methods. These methods allow entering any Unicode code point using hexadecimal notation. Some methods work only when editing worksheet cells, while others also work in dialog boxes.
2. Methods for Entering Unicode Characters
2.1 Alt+X Method (Cell Editing Only)
Enter a sequence of 1–6 hexadecimal digits and immediately press Alt+X. The digits are converted into the corresponding Unicode character.
Important: Any preceding valid hexadecimal digits that are not separated (e.g., by a space) will also be converted.
This method is available only when editing worksheet cells. It is not available in dialog boxes.
2.2 Ctrl+Shift+U Method
Press Ctrl+Shift+U, then type a sequence of 1–6 hexadecimal digits, and press Space to confirm.
This method works in more contexts than Alt+X and does not require cell‑editing mode.
2.3 Alt + Hexadecimal Code (Hex Numpad)
Press and hold Alt, press + on the numeric keypad, enter the hexadecimal Unicode code, then release Alt.
This method may require enabling the Windows Hex Numpad feature by adding the following registry key:
HKEY_CURRENT_USER\Control Panel\Input Method\EnableHexNumpad
Set the value to "1" (type: REG_SZ).
