On a PC keyboard (Windows), is there a method, without having to install additional software, to enter any Unicode character using its code point in decimal?
Alt + ABCD does it in hexadecimal, but I am looking for a method for decimal numbers. Hexadecimal numbers require using keys outside the numeric keypad, and a combination of some letters with the Alt key may cause unintended side effects. For example, Alt + F in Notepad will open the File menu making it impossible to enter the hexadecimal f character.
