Exporting to html - problem with encoding

Online experiments

I’ve found unexpected error while exporting procedure from PsychoPy v1.85.1 to html. It seems that there is a problem with encoding. However I don’t know how to deal with it.

Any ideas?

Welcome to PsychoPy2!

We’ve managed to circumvent the problem by throwing out text content of TextStim objects (which contained non-ascii characters). Is this something that was solved recently (I have a vague recollection that it was mentioned on github some time ago)?

Ah, looks like there’s still a reference to str() that shouldn’t be there. Maciek, could you try editing the file
/Applications/PsychoPy2.app/Contents/Resources/lib/python2.7/psychopy/app/builder/components/__init__.py and replacing all instances of:

str(

with

unicode(

Ok, I’ve found 2 instances of

str(

and replaced it with

unicode(

as you suggested. After that PsychoPy do not inform about any error during exporting to html and index.html file is being successfully been created. It seems that everything is just fine. Thank You!
