ExtractText

Hello,

We recently upgraded to Aspose.Pdf.Kit 3.6.0.0 and we are getting different results extracting the text from PDF files. What are the characters (see attached "Extracted text.txt") that show before every number for the text extracted from the attached "Test 16.pdf"? These characters are making our application behave different to before the upgrade.

Our code snippet,

PdfExtractor extractor = new PdfExtractor();

extractor.BindPdf(path);

extractor.ExtractText();

MemoryStream os = new MemoryStream();

extractor.GetText(os);

string s = new UnicodeEncoding().GetString(os.ToArray());

os.Close();

Thanks,

Juno

Hi Juno,

I have tested this file with with 3.5, 3.6 and 3.8 and result is the same with all of these. In fact, it is not the problem with the component, rather the file contains CR and LF characters as \r and \n, which represent carriage return and new line feed. These characters are the part of the PDF content. So, if you don’t want these characters in the extracted text, you can replace with string replace method in your code, once the text is extracted.

I hope this helps. If you still have any questions or find some problems, please do let us know.

Hello,

The carriage return and new line are fine, I was talking about the characters before the numbers, please see attached 'Extracted text.bmp'.

Thanks,

I cannot see what are we doing differently. Please see attached another file I have the same problem with.

After looking at some other PDF files, I'm basically seeing the character with code 65279 at the beginning of each page for any PDF (see another example attached).

Hello,

After replacing Aspose.Pdf.Kit with the latest version (3.9.0.0) I'm still getting the unicode byte order mark at the beginning of the text extracted from any PDF page. I opened Windows process explorer while running our application an it shows the latest version of Aspose.Pdf.Kit (3.9.0.0). Is there something else I can check to make sure I'm using the correct dll?

Thanks,

Juno

Hi Juno,

We’re looking into this problem and you’ll be updated the earliest possible.

We’re sorry for the inconvenience.

Hello,

Is it safe to assume that the unicode bom is going to be at the beginning of the text extracted from each page for **any** PDF? We may have to patch our code to ignore the bom if the fix for this takes much longer.

Thanks,

Juno
