This article will guide you through fixing this problem using Ghostscript for PDF conversion, allowing you to successfully extract readable text from Urdu and Arabic documents.
Understanding the Problem
When converting a PDF document to text format, the result can be unreadable due to character encoding issues. This is particularly common in non-Latin scripts such as Urdu and Arabic. To address this challenge, using the right tools and configuration settings is crucial.

Using Ghostscript for Urdu and Arabic Documents
To convert a PDF document containing Urdu or Arabic text using Ghostscript, you will need to configure the software appropriately. This includes specifying the correct fonts and character encoding.
# Convert a PDF document with Urdu or Arabic text

By adding the -sCoding=Identity-H option in the command above, you can ensure that the characters in the output text file will be represented correctly.
Handling Complex Layouts and Diacritics
Urdu and Arabic documents can have complex layouts and include diacritical marks. These elements can cause additional complications during conversion. Here are some tips to help you deal with these issues:
- Make sure that the PDF document is clean and well-structured. This will make it easier to extract the text.
- Apply proper text preprocessing, such as removing unnecessary characters or correcting diacritics if needed.
- If required, post-process the extracted text to improve its readability or structure.
Converting a PDF document in Urdu or Arabic to a text file using Ghostscript requires proper configuration settings. The -sCoding=Identity-H option should be added to the command, ensuring correct character encoding. Additionally, handling complex layouts and diacritics requires a clean PDF document, text preprocessing, and/or post-processing.
