title: How should I handle "above the range (U+0000-U+FFFF) allowed by Tcl"?
body: <p>It is a known problem of Tkinter/Tcl in Python3 that it only supports characters between <code>U+0000-U+FFFF</code>.</p>
  
  <p>There are some solutions around parsing strings and replacing the not allowed characters with placeholders or codes. But I have to know that there is a disallowed character in before this make sense.</p>
  
  <p>Do I really have to use this parsing-replacing-algorithms for every string I put in my Tkinter GUI? The essential point of my question is that I have data (webfeeds) I don't know. Do I have to parse this big amount of data only because one of some millions of this data pieces use unallowed characters?</p>
  
  <p>Is there a pythonic way to solve this? Can I use parsing-replacing-algorithms without wasting too many resources?</p>
  
  <pre><code>#!/usr/bin/env python3
  
  from tkinter import *
  
  if __name__ == '__main__':
      root = Tk()
  
      l = Listbox(root)
      l.pack()
  
      d = ['A', 'B', u'\U0001F384', 'D']
  
      for s in d:
          l.insert(END, s)
  
      root.mainloop()
