Error callstack

Trac detected an internal error: UnicodeEncodeError: 'ascii' codec can't encode characters in position 227-230: ordinal not in range(128)

I believe this error is caused by this changeset ​http://genshi.edgewall.org/changeset/1140

I try to call stream_milestones.render() instead of str(stream_milestones)

html_milestones = str(stream_milestones)
html_milestones = stream_milestones.render()

And this fix this probelm

Thanks. Applying this patch it still works for me, too. My question is to you: Is render() available for older versions or could it break something?

[Ryan J Ollos]

I think you should be okay to call render:

• ​Genshi 0.6
• ​Genshi 0.5

In 13138:

Fixed #10989: call render() instead of str() in __extract_div_milestones_array() to avoid UnicodeEncodeError (Thanks to ykrocku for the patch and rjollos for reviewing).
