How to I go about indexing & searching Chinese text using Solr?

I have a pile o' simplified Chinese text encoded in UTF-8. Taking hints from some Solr documentation [1], I have configured my index thusly:

  <schema name="hui" version="1.6">
    <uniqueKey>key</uniqueKey>

    <!-- local field types -->
    <fieldType name="string" class="solr.StrField" sortMissingLast="true" docValues="true"/>
    <fieldType name="long" class="solr.TrieLongField" positionIncrementGap="0" docValues="true" precisionStep="0"/>
    
    <!-- chinese indexing configuration happens here -->
    <fieldType name="text_general" class="solr.TextField">
      <analyzer>
        <tokenizer class="solr.HMMChineseTokenizerFactory"/>
        <filter class="solr.CJKWidthFilterFactory"/>
        <filter class="solr.StopFilterFactory"
          words="org/apache/lucene/analysis/cn/smart/stopwords.txt"/>
        <filter class="solr.PorterStemFilterFactory"/>
        <filter class="solr.LowerCaseFilterFactory"/>
      </analyzer>
   </fieldType>

    <!-- good to have fields -->
    <field name="_root_"    type="string"       docValues="false"   indexed="true" stored="false"/>
    <field name="_text_"    type="text_general" multiValued="true"  indexed="true" stored="false"/>
    <field name="_version_" type="long"         indexed="true"      stored="false"/>
  
    <!-- my fields -->
    <field name="fulltext" type="text_general"  multiValued="false"  indexed="true"   stored="true" />
    <field name="key"      type="text_general"  multiValued="false"  indexed="true"   stored="true"  />

    <!-- cool field -->
    <copyField source="*" dest="_text_"/>
  
  </schema>

I then index my content, and as per the Solr Admin interface, my index includes 130 documents. I then have problems searching:

  * Using the Solr Admin interface, I can search for everything (*:*), and all my results are returned, but the Chinese characters are all mangled.

  * Using a Lynx (terminal) interface, I can search for everything (*:*), and all my results are returned, but the Chinese characters are all mangled.

  * Using a Perl interface of my own design, I can search for everything (*:*), and get results and the characters are NOT mangled.

  * Using the same Perl interface, I try to enter a query using Chinese characters, but I always get zero results.

  * Using the same Perl interface, I can search for the word "body" (an HTML element I didn't delete), I get expected results.

  * Using the same Perl interface, I an enter a query using the mangled characters, and I get the sorts of results I expect.

I believe I have indexed my documents "correctly", but I can't seem to query the index in the expected manner. What might I be doing wrong?
