> I am able to successfully index/search non-Engilsh files (like Hebrew, Ja=
panese) which was encoded in UTF-8. However, When I tried to index data whi=
ch was encoded in local encoding like Big5 for Japanese I could not see the=
 desired results. The contents after indexing looked garbled for Big5 encod=
ed document when I searched for all indexed documents. When I index attache=
d 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 g=
ets 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.
> For more reference below is the discussion with Yonik.
>     Please find attached TXT file which I was using to index and search.
>     curl "http://localhost:8983/solr/update/extract?literal.id=3Ddoc1&upr=
efix=3Dattr_&fmap.content=3Dattr_content&fmap.div=3Dfoo_t&boost.foo_t=3D3&c=
ommit=3Dtrue&charset=3Dutf-8" -F "myfile=3D@sample_jap_non_UTF-8"
> One problem is that you are giving big5 encoded text to Solr and saying t=
hat it's UTF8.
> Here's one way to actually tell solr what the encoding of the text you ar=
e sending is:
> curl "http://localhost:8983/solr/update/extract?literal.id=3Ddoc1&uprefix=
=3Dattr_&fmap.content=3Dattr_content&fmap.div=3Dfoo_t&boost.foo_t=3D3&commi=
t=3Dtrue" --data-binary @sample_jap_non_UTF-8.txt -H 'Content-type:text/pla=
in; charset=3Dbig5'
> Now the problem appears that for some reason, this doesn't work...
> Could you open a JIRA issue and attach your two test files?
