Workbook Save as PDF doesn't use glyph substitution correctly


  1. Example xlsx to show the case that character U0E49 will be replaced by glyph202 (see C2 and D2).
  2. The pdf generated by Aspose.Cells doesn’t use glyph202 correctly.
  3. Thai font, Angsana, that has glyph substitutions.
  4. Picture to show the U0E49 substitution example in FontForge.

Thanks for the template file and screenshot.

Please notice, after an initial test, I am able to reproduce the issue as you mentioned by converting your template file to PDF. I found when saving Excel file to PDF, it does not use glyph substitution correctly. I have logged a ticket with an id “CELLSNET-50644” for your issue. We will look into it soon.

Once we have an update on it, we will let you know.
