ClassicAnalyzer Behavior on accent character

[Chitra]

Hi,
              I indexed a term 'ⒶeŘꝋꝒɫⱯŋɇ' (aeroplane) and the term was
indexed as "er l n", some characters were trimmed while indexing.

Here is my code

protected Analyzer.TokenStreamComponents createComponents(final String
fieldName, final Reader reader)
    {
        final ClassicTokenizer src = new ClassicTokenizer(getVersion(),
reader);
        src.setMaxTokenLength(ClassicAnalyzer.DEFAULT_MAX_TOKEN_LENGTH);

        TokenStream tok = new ClassicFilter(src);
        tok = new LowerCaseFilter(getVersion(), tok);
        tok = new StopFilter(getVersion(), tok, stopwords);
        tok = new ASCIIFoldingFilter(tok); // to enable AccentInsensitive
search

        return new Analyzer.TokenStreamComponents(src, tok)
        {
            @Override
            protected void setReader(final Reader reader) throws IOException
            {

src.setMaxTokenLength(ClassicAnalyzer.DEFAULT_MAX_TOKEN_LENGTH);
                super.setReader(reader);
            }
        };
    }


Am I missing anything? Is that expected behavior for my input or any reason
behind such abnormal behavior?
