New submission from Serhiy Storchaka:
When open the About IDLE dialog and press the README button on bottom line, I
get the UnicodeDecodeError:
Exception in Tkinter callback
Traceback (most recent call last):
File "/home/serhiy/py/cpython/Lib/tkinter/__init__.py", line 1548, in __call__
return self.func(*args)
File "/home/serhiy/py/cpython/Lib/idlelib/aboutDialog.py", line 127, in
ShowIDLEAbout
self.display_file_text('About - Readme', 'README.txt')
File "/home/serhiy/py/cpython/Lib/idlelib/aboutDialog.py", line 139, in
display_file_text
textView.view_file(self, title, fn, encoding)
File "/home/serhiy/py/cpython/Lib/idlelib/textView.py", line 74, in view_file
contents = file.read()
File "/home/serhiy/py/cpython/Lib/codecs.py", line 321, in decode
(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x92 in position 72:
invalid start byte
That is because IDLE opens the Lib/idlelib/README.txt file with default
(locale) encoding, while it contains the RIGHT SINGLE QUOTATION MARK character
encoded with the CP1252 encoding and non-decodable with UTF-8.
I think IDLE should open all distributed files with UTF-8 encoding.
Lib/idlelib/CREDITS.txt and Lib/idlelib/README.txt should be recoded to UTF-8.
