Problem with tk.Tk() and æ ø å in Windows username

[torquil]

Bug report

Bug description:

I wonder if this problem occurs because my Windows username not not pure ascii?

I do know that there is an __init__.py in the folder C:/Users/TorquilSørensen/anaconda3/Library/lib/tcl8.6

I'm using Python 3.13.9 from Anaconda on Windows 11:

Example of Python output when trying to use tk.Tk() inside Spyder 6.1.0:

import tkinter as tk

root = tk.Tk()
---------------------------------------------------------------------------
TclError                                  Traceback (most recent call last)
Cell In[2], line 1
----> 1 root = tk.Tk()

File ~\anaconda3\Lib\tkinter\__init__.py:2465, in Tk.__init__(self, screenName, baseName, className, useTk, sync, use)
   2463         baseName = baseName + ext
   2464 interactive = False
-> 2465 self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)
   2466 if _debug:
   2467     self.tk.settrace(_print_command)

TclError: Can't find a usable init.tcl in the following directories: 
    C:/Users/TorquilSørensen/anaconda3/Library/lib/tcl8.6 C:/Users/TorquilSørensen/lib/tcl8.6 C:/Users/lib/tcl8.6 C:/Users/TorquilSørensen/library C:/Users/library C:/Users/tcl8.6.15/library C:/tcl8.6.15/library



This probably means that Tcl wasn't installed properly.

CPython versions tested on:

3.13

Operating systems tested on:

Windows

Can you try with the latest release of Python 3.14, 3.14.7? It updated to Tcl/Tk 9.0.4, which I suspect might handle this better. I don't think we'll be backporting that update to 3.13 at this point.

Our windows installer puts tcl files, including a tcl8.6 in a tcl directory inside the install directory (the one including python.exe). There is no __init__.py there. The n thousand line tkinter __init__.py is in Lib/tkinter. Anaconda appears to handle tcl differently. Please direct your question to anaconda help resources. You might also search web for something like anaconda "<error message>".
