patch 8.0.1467: libvterm doesn't handle illegal byte sequence correctly

Problem:    Libvterm doesn't handle illegal byte sequence correctly.
Solution:   After the invalid code check if there is space to store another
            character.  Allocate one more character. (zhykzhykzhyk, closes
            #2614, closes #2613)
