winapi: how to add unicode character according to it's unicode-number?

[Dave11]

for example - if I have LPWSTR or LPTSTR or even wchar_t variable -
and I would like to add into these strings or assign the single variable the unicode character which code is u+1f37a (beer mug) - how do I do it ? I tried looking for code->character function in the winapi but i did not find any.
any ideas guys?
thanks in advanced.
