On master 1144388 %running:

# -*- coding: ISO-8859-1 -*-

as a script from the regular ipython console I get:

AttributeError                            Traceback (most recent call last)
C:\python\external\ipy-bugs\run_qtcons_bug.py in <module>()
      3 a=[]
----> 4 a.apppend(u"åäö")

AttributeError: 'list' object has no attribute 'apppend'

from qtconsole I get a long traceback that ends in:

c:\python26\lib\json\encoder.pyc in _iterencode(self, o, markers)
292                     and not (_encoding == 'utf-8')):
293                 o = o.decode(_encoding)
--> 294             yield encoder(o)
295         elif o is None:
296             yield 'null'
UnicodeDecodeError: 'utf8' codec can't decode byte 0xe5 in position 292: invalid continuation byte

Can you put the full traceback in a pastebin somewhere, and give a link to it?


OK, I think the issue is that we read the file without worrying about its encoding. That's fine at the terminal, where we can just dump it back out without trying to encode or decode it. It's more complicated for sending it as JSON.

Oops pushed the wrong button. Did not mean to close it.


This one, at least, I can replicate. I think it may have to wait for an overhaul of the exception handling code, though. In the meantime, ensure that your editor is set to save in UTF-8.

This should be fixed by PR #770
