generated transliterations contain different version of the s character

[romanchyla]

for some mysterious reason, our transliterations contain the 'other' s

the query:

In [29]: repr(u'author:"Işık, Emre"')
Out[29]: 'u\'author:"I\\u015f\\u0131k, Emre"\''

solr record:

In [30]: repr(u'işık, e')
Out[30]: "u'i\\u015f\\u0131k, e'"

In [31]: repr(u'işık, emre')
Out[31]: "u'i\\u015f\\u0131k, emre'"

our transliterations (got \u0326 instead of \u015f):

In [32]: repr(u'isik\,\ emre=>ișık\,\ emre,ișik\,\ emre,ișık\,\ emre')
Out[32]: "u'isik\\\\,\\\\ emre=>is\\u0326\\u0131k\\\\,\\\\ emre,i\\u0219ik\\\\,\\\\ emre,i\\u0219\\u0131k\\\\,\\\\ emre'"

In [33]: repr(u'șșş')
Out[33]: "u's\u0326\u0219\u015f'"
