UnicodeEncodeError while pressing a ListItemButton #3078

alexkiro · 2015-02-25T10:26:08Z

While having an unicode character in a ListItemButton's text is working ok, the application crashes when the button is pressed:

Kivy version:

$ pip freeze | grep -i kivy
Kivy==1.8.0

The text was updated successfully, but these errors were encountered:

The error can be replicate with this simple modified kivy example:

@alexkiro Your pastebin example needs fixing. Can you make it runnable ? I get multiple python syntax errors.

alexkiro · 2015-02-25T10:36:16Z

@victor-rene

Works fine for me :/

@alexkiro

Should not work though. What I did to fix it is add

 #!/usr/bin/env python

at the top of your script. Then remove u"_______" before "chérie" and "Middle-{0}"
You must be more precise / careful before opening an issue =).

Aside from this it works for me on Windows with 1.8.0. No problem clicking a list item. Should be closed.

#!/usr/bin/env python

It should work just fine without the shebang if you pass it trough python yourself.

Then remove u"_______" before "chérie" and "Middle-{0}"
You must be more precise / careful before opening an issue =).

This was just a simple example to replicate the issue. I received the data I want to present in the list as unicode. Removing the u is not a solution here.

I can encode the data before setting it to the ListItemButton, but the button should be able to handle unicode strings just fine. For example the documentation for Label states that (http://kivy.org/docs/api-kivy.uix.label.html).

I still believe this is an issue that requires fixing. Or at least clean-up what kind of string does the Widget accept.

@alexkiro

What I am saying is if you wish the issue to be fixed, provide a better example. As such I am not able to reproduce it, without modifying your pastebin. Secondly, there was a lot of work done to fix unicode issues in the dev version (1.9.0). I would like to investigate this further but your example isn't clear enough for me at this point. It would make things easier for everyone if you reworked it, so we can test on stable / dev and other platforms to confirm if there is an issue or if it's solved by 1.9.0-dev implementation.

alexkiro · 2015-02-25T11:35:20Z

Hmm, sorry, I'm still not sure what is not clear here :(

I'll install the dev version and checked if this has been already fixed. The traceback also point to this part of the code (in kivy.lang):

def call_fn(*args):
    if __debug__:
        trace('Builder: call_fn %s, key=%s, value=%r, %r' % (
           element, key, value, rule.value))

This suggests that the issue only occurs when -O flag is not used. And indeed running the app with -O avoids this problem:

$ python -O test_list.py

alexkiro · 2015-02-25T11:45:42Z

Update, this has been indeed fixed in the latest dev version:
