Tue Aug 26 11:06:22 2014] [error] [client 192.168.21.146] File "/opt/lang/python/virtualenvs/3.4/bi/lib/python3.4/site-packages/webassets/merge.py", line 60, in save [Tue Aug 26 11:06:22 2014] [error] [client 192.168.21.146] f.write(self.data()) [Tue Aug 26 11:06:22 2014] [error] [client 192.168.21.146] UnicodeEncodeError: 'ascii' codec can't encode character '\\xa0' in position 158569: ordinal not in range(128)

The fopen method fails to set the encoding when writing bytes back out to the cached file.

def save(self, filename):
    with open(filename, 'w') as f:
        f.write(self.data())

I will be submitting a pull request for this.

Meant to put this to the webassets project, my bad.
