Android: String class's equals method behave abruptly

Question

I am reading a text file and from that I am inserting a value suppose ID=1s001(String) in the data base. And I am again reading files but this time I want to make sure that I read files if the ID is different in these file, for that I am reterving value from db and comparing with current ID.

Like this Id (from deb). equals (current ID)

But unfortunatily even if the ID=1s001 equals method returns false.

only thing I was able to find is that currentID.length=6 & Id (from deb).length is returning 5. I don't know what is causing this? any Idea?

Actual Code:

Cursor cursor = database.query(StorageDataBase, allColumns,
                null, null, null, null, null);
        int count = cursor.getCount();

        if(count>0){
            if(cursor.moveToFirst())
            {
                String slsManCode=cursor.getString(cursor.getColumnIndex("sales_man_id"));
                System.out.println(slsManCode.length()+"            "+salesManCode.length());
                boolean is=slsManCode.trim().equals(salesManCode.trim());

                                if(slsManCode.contains(salesManCode))
                {
                    return true;
                }

Every coloumn in db is text.

我已经知道是什么原因造成的，实际上这是一个编码问题。
