Hello Support,
I also have a Khmer PDF render issue and noticed this thread.
Whatever I try I cannot make it work. Could you please help/advise?
Here is my code:
import aspose.words as aw
from aspose.words.saving import PdfSaveOptions, PdfCompliance, PdfFontEmbeddingMode, PdfTextCompression
file = r'test_file.docx'
output = r'test_file.pdf'
doc = aw.Document(file)
pdf_options = aw.saving.PdfSaveOptions()
pdf_options.embed_full_fonts = True
pdf_options.compliance = PdfCompliance.PDF_A1A
pdf_options.update_fields = True
pdf_options.embed_full_fonts = True
pdf_options.jpeg_quality = 100
pdf_options.allow_embedding_post_script_fonts = True
pdf_options.font_embedding_mode = PdfFontEmbeddingMode.EMBED_ALL
pdf_options.text_compression = PdfTextCompression.NONE
pdf_options.preserve_form_fields = True
doc.save(output, pdf_options)

@rob2902 Thank you for additional information. To get Khmer text rendered closer to MS Word it is required to enable open type features. In .NET version of Aspose.Words Aspose.Words.Shaping.Harfbuzz package provides support for OpenType features in Aspose.Words using the HarfBuzz text shaping engine. unfortunately, this feature is not yet provided in Python version of Aspose.Words.

PS: Here is PDF document produced by Aspose.Words for .NET with open type features enabled: out_HarfBuzz.pdf (6.3 KB)
Thank you for the feedback.
Could you please advise which languages are not supported in the Python version of Aspose.Words?
I’m asking because we’re seeing more rendering issues with certain scripts (e.g., Hindi, Marathi, Gujarati, Punjabi, Tamil, Malayalam, Bengali, Telugu, Kannada, Oriya). Do these languages also require OpenType features for correct rendering?
Thank you in advance.
@rob2902 The feature is already implemented in Python version of Aspose.Words. Please use LayoutOptions.enable_text_shaping property to enable open type features upon rendering the documents.
Thank you @alexey.noskov! I assume this feature was implemented recently? Could you confirm please which Aspose.Words version is required to use this?
@rob2902 The feature is available starting from 26.2 version of Aspose.Words. For some reason auto-notification was not posted in this thread. Please accept our apologies for this.
