Reading user input using UniCurses for Python

Question

How do I properly read user input using unicurses?

I am using wgetstr to read in user input, but how would I go about making sure that the input does not flow over to the next line. The input should just stop when the last character reaches the end of the window.

Currently:

import unicurses as uc

def read(window)
    st = uc.wgetstr(window)
    return st.decode('utf-8')

I'm not really willing to move over to curses or ncurses since I have an almost fully fuctional (minimal) library built around unicurses.
