Unable to display Devanagari ligatures correctly in python tkinter

[Anamika]

I am trying to display Devanagari (Hindi) text in python3 tkinter. I find that the display of text is incorrect in tkinter for all the widgets capable of holding text. The problem remains for any Truetype font with Unicode support. I have tried "Noto Sans", "Gargi", "Sankrit 2003" and some more Devanagari fonts.

This does not seem to be a problem with the font because -
i) I am getting correct display with any of the above fonts on ubuntu terminal (image attached)
ii) The text display is correct in html
iii) The problem appeared in python fpdf. But it got resolved when the flag set_text_shaping was set to TRUE.

The code is as under :

from tkinter import *
root = Tk()
print(TkVersion)
T = Text(root, height = 5, width = 52)
T.config(font =("Gargi", 20))
l = Label(root, text = "Errors in Devanagari display")
l.config(font =("Gargi", 20))
l.pack()
T.pack()
T.insert(END, "   संधिस्थापनके प्रयत्नका औचित्य बताना..")
root.main

I have attached images of correct display as well as erroneous display. Correct display is also seen in the code snippet above.

Any help towards resolving the issue would be thankfully received. If this has already been addressed / discussed in this forum, a link to that topic may please be provided. Thanks in advance.

Devanagari is not one of the fonts in tkinter. To use Devanagari you need to import it as a custom font. There was a post about importing fonts in tkinter.

Importing the custom font from the ttf file has not resolved the issue. However, some users on another forum have mentioned that the code I attached has worked for them correctly on their platforms. I am unable to think of a way forward.

You can use custometkinter to load ttf fonts.
List of fonts that I got to work

• Devanagari Plain9190 122439 PM.ttf
  
• Ganga 1 Regular.ttf
  
• Kruti Dev 714 Normal.ttf
  
• Maiya Regular.ttf
  
• Manishau Regular.ttf
  

import customtkinter as tk

app = tk.CTk()
app.configure(padx=10, pady=8)
tk.FontManager.load_font('Maiya Regular.ttf')

label = tk.CTkLabel(app, text='Hello World!', font=('Maiya', 48))
label.pack()

app.mainloop()

AFAIK, fonttools https://pypi.org/project/fonttools/ is required to use additional fonts in Python. There is a way to do this using PIL and a canvas widget https://www.devgem.io/posts/displaying-d...mon-issues
