Chess pieces Unicode tkinter font issues

I'm working on a chess-based game in Python 3 using tkinter windows. I'm using the Unicode characters for chess pieces. However, they have two different looks (as seen here: https://en.wikipedia.org/wiki/Chess_symbols_in_Unicode). I want to use the top one, but no matter what font I use, the ugly bottom version appears. What am I doing wrong?

Edit: It would be more convenient to use a monospaced font

Solution

The problem is likely that tkinter can't find the font you specified, or the font you specified doesn't have the unicode glyphs, so it's substituting in a font that has the glyphs.

Here's a little program that will show you all of the fonts on your system, and what the chess pieces look like:

import sys
if sys.version_info.major is 3:
    import tkinter as tk, tkinter.font as tkFont
else:
    import Tkinter as tk, tkFont

root = tk.Tk()
text = tk.Text(root, tabs=(200,))
vsb = tk.Scrollbar(root, command=text.yview)
text.configure(yscrollcommand=vsb.set)
vsb.pack(side="right", fill="y")
text.pack(side="left", fill="both", expand=True)

pieces = u"\u2654\u2655\u2656\u2657\u2658\u2659\u265A\u265B\u265C\u265D\u265E\u265F\n"
for count, family in enumerate(sorted(tkFont.families())):
    font = tkFont.Font(family=family, size=18)
    tag = "font-%s" % count
    text.tag_configure((tag,), font=font)
    text.insert("end", family)
    text.insert("end", "\t" + pieces, tag)

root.mainloop()
