                 Key: SOLR-2346
                 URL: https://issues.apache.org/jira/browse/SOLR-2346
             Project: Solr
          Issue Type: Bug
          Components: contrib - Solr Cell (Tika extraction)
    Affects Versions: 1.4.1
         Environment: Solr 1.4.1, Packaged Jetty as servlet container, Wind=
ows XP SP1, Machine is booted in Japanese Locale.
            Reporter: Prasad Deshpande
            Priority: Critical


I am able to successfully index/search non-Engilsh files (like Hebrew, Japa=
nese) which was encoded in UTF-8. However, When I tried to index data which=
 was encoded in local encoding like Big5 for Japanese I could not see the d=
esired results. The contents after indexing looked garbled for Big5 encoded=
 document when I searched for all indexed documents. When I index attached =
non utf-8 file it indexes in following way

- <result name=3D"response" numFound=3D"1" start=3D"0">
- <doc>
- <arr name=3D"attr_content">
  <str>=EF=BF=BD=EF=BF=BD =EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=
=BF=BD</str>
  </arr>
- <arr name=3D"attr_content_encoding">
  <str>Big5</str>
  </arr>
- <arr name=3D"attr_content_language">
  <str>zh</str>
  </arr>
- <arr name=3D"attr_language">
  <str>zh</str>
  </arr>
- <arr name=3D"attr_stream_size">
  <str>17</str>
  </arr>
- <arr name=3D"content_type">
  <str>text/plain</str>
  </arr>
  <str name=3D"id">doc2</str>
  </doc>
  </result>
  </response>

Here you said it index file in UTF8 however it seems that non UTF8 file get=
s indexed in Big5 encoding.
Here I tried fetching indexed data stream in Big5 and converted in UTF8.

String id =3D (String) resulDocument.getFirstValue("attr_content");
            byte[] bytearray =3D id.getBytes("Big5");
            String utf8String =3D new String(bytearray, "UTF-8");
It does not gives expected results.

When I index UTF-8 file it indexes like following

- <doc>
- <arr name=3D"attr_content">
  <str>=E3=83=9E=E3=82=A4 =E3=83=8D=E3=83=83=E3=83=88=E3=83=AF=E3=83=BC=E3=
=82=AF</str>
  </arr>
- <arr name=3D"attr_content_encoding">
  <str>UTF-8</str>
  </arr>
- <arr name=3D"attr_stream_content_type">
  <str>text/plain</str>
  </arr>
- <arr name=3D"attr_stream_name">
  <str>sample_jap_unicode.txt</str>
  </arr>
- <arr name=3D"attr_stream_size">
  <str>28</str>
  </arr>
- <arr name=3D"attr_stream_source_info">
  <str>myfile</str>
  </arr>
- <arr name=3D"content_type">
  <str>text/plain</str>
  </arr>
  <str name=3D"id">doc2</str>
  </doc>

So, I can index and search UTF-8 data.
