Description:	This program shows the bug: tk scaling 2 ttk::entry .e1 -placeholder "It is this" ttk::entry .e2 -placeholder "It’s this" grid .e1 -row 0 -column 0 grid .e2 -row 1 -column 0 bind . <Escape> exit If you run the program the first entry correctly shows `It is this` but the second entry wrongly shows `It’s this?n`, where the `?` is a box. If you vary the text (but include the apostrophe, ’, different numbers of boxes or n's appear.
