TextStamp color removed when includes special characters

Hello,
I am using Aspose.words to generate pdf.
I have the following method that adds a header stamp to my documents when we download them:

private TextStamp createHeaderStamp(String headerStamp) {

	TextStamp textStamp = new TextStamp(String.format("%s", headerStamp));
	textStamp.getTextState().setFontSize(8);
	textStamp.getTextState().setFontStyle(FontStyles.Regular);
	textStamp.getTextState().setForegroundColor(Color.getGray());
	textStamp.setOpacity(0.5);
	textStamp.setVerticalAlignment(VerticalAlignment.Top);
	textStamp.setHorizontalAlignment(HorizontalAlignment.Left);
	textStamp.setLeftMargin(5);
	textStamp.setTopMargin(5);
	LOGGER.info("Header text stamp {}", textStamp.getValue());
	return textStamp;
}

As you can see, we set the color of the text to grey.

I am now facing a strange bug:
When the text contains contains special characters (for example važeća in Croatian), the textStamp is added in color white and seams invisible.

I’ll truly appreciate your review.
Thank you.

@LeahGreen The code you have provided is not related to Aspose.Words. It looks like you are using Aspose.PDF to ass text stamps to your PDF documents. I will move your topic to the appropriate forum. My colleagues will help you shortly.

Ok. Thanks.
I currently can’t share the output file, because it contains some other data that shouldn’t be visible to public.
If there is a way to share it privately I’ll appreciate it.

We testing using 24.12 version of the API and could not replicate the issue in our environment. Please check attached output PDF document.

We need sample source PDF to replicate the issue in our environment. Hence, sending you a private message where you can share your file.
