[Tkinter-discuss] Canvas.postscript() fails to render some fonts properly

[Firat Ozgul]

Hello,

It seems to me that for the most part, you are having issues with font names
that have spaces between the words making up the font name. For example:
"DejaVu Sans Condensed"

If there are spaces between words, you should define self.font as a tuple:

self.font = ("DejaVu Sans Condensed",)

Note the trailing comma in accordance with the rules of creating a
one-element tuple...

Although it is not mandatory, you would better use the exact same cases
(uppercase vs lowercase) for the fonts as seen from the output of:

[code]
root = Tk()
root.tk.call("font", "families")
[/code]

Please try this way, and tell me if it solves the problem.
