Arabic diacritics problem

I have purchased aspose.word product :

When we use “traditional Arabic” font and our document contains “Arabic diacritics (Tashkeel)” the generated pdf output became different than word (little space added between arabic letters ).

Please find the 2 attachments for screenshot of word and pdf:

this is the paragraph that has the issue :
أقْرَأُْ قِراءَةً صَحيحَةً مُحَرَّكَةً : لُبنَانُ وَطَنٌ حُرٌّ مُسْتَقِلٌّ ، نُرِيدُ أَنْ نَعيشَ شَعْباً سَيِّداً سَعِيداً ، في وَطَنٍ حُرٍّ مُسْتَقِلٍّ . كَتَبْتُ فَرْضاً نَظيفاً بِخَطٍّ جَميلٍ، وَدَرَسْتُ أُمْثُولَةً ، لَمْ تَكُنْ صَعْبَةً وَلَكِنَّها طَوِيلَةٌ . في يَوٍمِ عُطْلَةٍ قُمْنَا بِنُزْهَةٍ ، مَسَافَةٍ طَويلَةً مِنْ غَيْرِ تَعِبٍ ، وَقَدْ شَجَّعَنا على ذَلِك ، طَقٍسٌ جَميلٌ ، وَشَمْسٌ مُشْرِقَةٌ ، وَجَوٌّ مُعْتَدِلٌ


Thanks for your inquiry. Please note that Aspose.Words requires TrueType fonts when rendering document to fixed-page formats (JPEG, PNG, PDF or XPS). You need to install fonts that are used in your document on the machine where you’re converting documents to PDF. Please refer to the following article:
