Rather than raising a ValueError, would UnicodeEncodeError be more appropriate?
I admit that this suggestion may be bike shedding.

I agree with Terry. The current behavior of raising ValueError will lead to
problems in application code in the future if Tkinter gets fixed such that it
can render Unicode properly beyond 0x.

Terry J. Reedy tjre...@udel.edu added the comment:
In responding to #14200, it occurred to me that better than an exception would
be doing what the interpreter does in Command Prompt window, which is expand
high chars to '\U0001' escaped form.

I'm not sure whether the wording is good English, but apart from that, the

You could say Unicode character ... in the error to make clear what kind of
range is U+-U+ (people that are not familiar with Unicode and BMP chars
might wonder if that's some tcl/tk thing).

Changing the error message sounds fine to me.
People in need of the feature should lobby their system vendors to provide a
Tcl build that uses a 32-bit Tcl_UniChar. Not sure whether it would actually
render the string correctly, but at
STINNER Victor victor.stin...@haypocalc.com added the comment:
Instead of
ValueError: unsupported character
I suggest:
ValueError: unsupported character (U+1): Tcl doesn't support characters
outside U+-U+ range
What do you think?

Slightly shorter and without the double :s.
ValueError: character U+1 is above the range (U+-U+) allowed by
Tcl/Tk.
I agree

Judging from the stack trace, it isn't str.format that's failing, it's tk
failing to display it.

U+1 is not the most common character in fonts. You should try another
character in U+1-U+10 range (non-BMP characters). The new funny
emoticon are in this range, but I don't know if your Ubuntu setup includes a

Ned Deily n...@acm.org added the comment:
From the discussions here, http://wiki.tcl.tk/1364, it appears that Tcl 8.5
(and earlier) does not support Unicode code points outside the BMP range as in
this example. I don't think there is anything practical IDLE or tkinter can do
about that.

It looks like that error message has been in _tkinter.c since 2002:

I suppose it could be slightly more informative but it seems pretty unambiguous
to me. Martin, any
