how to enter unicode characters in windows 7
Unicode input In order to enable a universal (independent of language settings) input method in Windows, one can add a string type (REG_SZ) value called EnableHexNumpad to the registry key HKEY_CURRENT_USER\Control Panel\Input Method and assign the value data 1 to it. Users need to log off/in on Windows 8.1/8.0, Windows 7, and Vista or reboot on earlier systems after editing the registry for this input method to start working. Unicode characters can then be entered by holding down Alt, pressing the + on the numeric keypad, followed by the hex code - using the numeric keypad for digits from 0 to 9 and letter keys for A to F digits - and then releasing Alt.[2] This may not work for 5-digit hex codes like U+1F937.
