Using 0.7.1 I'm getting:

In [12]: from scipy import io

In [13]: d = {'str':['test','test2','test34']}

In [14]: io.savemat('bug', d, format='4'); io.loadmat('bug')
Out[14]: 
{'__globals__': [],
 'str': array([u'test', u'test2', u'test34'], 
      dtype='<U6')}

In [15]: io.savemat('bug', d, format='5'); io.loadmat('bug')
Out[15]: 
{'__globals__': [],
 '__header__': 'MATLAB 5.0 MAT-file Platform: posix, Created on: Thu Jan 14 14:15:11 2010',
 '__version__': '1.0',
 'str': array([u'tttttt', u'e\x00e2e3', u's\x00s\x00s4'], 
      dtype='<U6')}

Works correctly in current master.
