content above is not a simple unicode string:
>>> from ttt.models import Content
>>> from django.template import loader
>>> c = loader.render_to_string('uni.html')
>>> c
u'\u2019'
>>> type(c)
<class 'django.utils.safestring.SafeUnicode'>
Copying it the way you did turns it into a simple unicode type:
>>> c2 = c[:]
>>> type(c2)
<type 'unicode'>
However, even the SafeUnicode version works for me:
>>> m=Content(content=c)
>>> m.save()

Yes, I am using MySQL backend. But I'm also using Django 1.1.1. I believe
the problem you have found here was found and fixed for ticket #6052:
http://code.djangoproject.com/ticket/6052
This fix went into the 1.0.X branch about a year ago. You really should run
the current 1.0.X release, not 1.0. Branch releases contain bug fixes
only, so there should be no concern about backwards incompatibilities in
upgrading to the latest branch release.
