O Windows suporta sequências Unicode, mas você precisará fazer um ajuste conforme descrito na Wikipedia :
[...] a user must set or create the registry key
HKCU\Control Panel\Input Method\EnableHexNumpad
with typeREG_SZ
to value1
and reboot (logging out and logging back in is sufficient). Once the registry key is set, the following method can be used to enter Unicode codepoints:Hold Alt and type the + key on the numeric keypad, then type the hexadecimal number (using the numeric keypad for digits 0-9 and the normal keys for a-f), then release Alt.
For example, Alt++11b will produce "ě" (e with caron).
