             Summary: Lucene.Net.QueryParsers.Flexible.Core.Util.UnescapedCharSequence
                 Key: LUCENENET-592
                 URL: https://issues.apache.org/jira/browse/LUCENENET-592
             Project: Lucene.Net
          Issue Type: Bug
          Components: Lucene.Net.QueryParser
    Affects Versions: Lucene.Net 4.8.0
         Environment: .NET 4.5.1/4.6.2
            Reporter: Greg Mulvihill


I noticed a few things that seem to be bugs in UnescapedCharSequence.cs.  

https://github.com/apache/lucenenet/blob/master/src/Lucene.Net.QueryParser/Flexible/Core/Util/UnescapedCharSequence.cs

Line 77: I found no reference to the private constructor UnescapedCharSequence(UnescapedCharSequence text), but needed to use it.

Line 81: The for loop throws an exception as the condition statement goes beyond the length of text due to '<=', rather than '<'.

Line 128: The for loop immediately terminates as i will always fail the condition statement.
