@zyx,
Thank you for the query. Unfortunately, I have not managed to reproduce the error. To investigate this case further, please share and specify the following:

  • comprehensive code example (FontConfig is an unknown symbol)
  • your external fonts that code example loads (FileConvertConstant.FONT_PATH)
  • your default font for replacing (FileConvertConstant.DEFAULT_FONT)
  • version of the OS on which the error appears
  • version of JDK that your application used
  • version of Aspose.Slides you used

But first, please check the issue with the latest version of Aspose.Slides.
