Note: Press the letter keys without holding shift, even though they are written as capital letters. You can type the numerical keys on the Numpad or on the row above the letters.

How to setup Windows for extended Unicode characters

[From https://superuser.com/posts/1024956/revisions

By default, the numeric keypad way of entering characters by code can only access the first 256 characters. (I believe these are defined by your system's code page for non-Unicode programs.) Codes bigger than 256 get wrapped around, so code 257 actually gets you character 1.

To enable the entry of all Unicode characters by code, create a string registry value in Computer\HKEY_CURRENT_USER\Control Panel\Input Method called EnableHexNumpad with the value of 1. Then you'll be able to enter any character by holding down the right Alt key, pressing the + button on the numeric keypad, entering the hex code (2, 7, 1, 3 in your case), and releasing the Alt key. You may need to log off and back on before this input type is enabled.

Note that the non-+ method of entering ASCII characters by code will continue to wrap around even after you enable this mode.

Step by step instructions:

1. Open Regedit. (Press Win+R. Type "regedit". Press enter.)
2. Select the current directory in the Regedit location bar and delete it. Copy and paste into it "Computer\HKEY_CURRENT_USER\Control Panel\Input Method"
Press enter to change the directory.
3. Right click on the empty space in the right panel. Select "New" from the context menu.
Click on "String value".
Enter "EnableHexNumpad" into the name.
Double click the new entry to edit it.
Type "1" in the "Value data" field. Click OK.
4. Log out of Windows and log back in.
