I have install:
TCL/Tk 8.4 (Tkinter-Files)
Problem at input of the text in widgets Tk.
English letters and figures are entered normally.
At input of Russian letters in an widgets there is a mistake: instead of the letter there is a figure or the English letter and the second symbol - a square.
The Russian text from a source code of the program is displayed normally.
For example: Button (root, text=u'привет ') .pack () All is correct, is displayed normally.
