The following exception has occurred when opening the file.

----

org.apache.poi.hssf.record.RecordInputStream$LeftoverDataException: Initialisation of record 0x894 left 10 bytes remaining still to be read.
	at org.apache.poi.hssf.record.RecordInputStream.hasNextRecord(RecordInputStream.java:156)

Error file has following conditions.

- Has named cell.
- Named cell has comment.
- Name of named cell or comment has multibyte characters.

I fixed NameCommentRecord as follows.

----
//Constructor.  NameCommentRecord(final RecordInputStream ris)
    if (in.readByte() == 0) {
        field_6_name_text = StringUtil.readCompressedUnicode(in, field_4_name_length);
    } else {
        field_6_name_text = StringUtil.readUnicodeLE(in, field_4_name_length);
    }
    if (in.readByte() == 0) {
        field_7_comment_text = StringUtil.readCompressedUnicode(in, field_5_comment_length);
    } else {
        field_7_comment_text = StringUtil.readUnicodeLE(in, field_5_comment_length);
    }

So I can read file.
I think the serialize method have to change too.

Please check my changes.

regards.
