Question about Japanese text support in HTML To PDF Conversion plug-in

Hello,

I am currently evaluating the HTML To PDF Conversion plug-in for generating PDF documents in Appian.

The basic conversion flow works correctly:

• I can pass an HTML file as the source document.

• The Smart Service generates a PDF document.

• The generated PDF can be saved in Appian.

However, I am having an issue with Japanese text.

The HTML file displays Japanese characters correctly when opened as HTML, but after converting it to PDF, the Japanese characters are rendered as #### in the PDF. English text and numbers are displayed correctly.

I have already tried the following, but the result did not change:

• Added <meta charset="UTF-8"/>

• Specified Japanese fonts in CSS, such as:

  • Noto Sans CJK JP

  • Noto Sans JP

  • Meiryo

  • Yu Gothic

  • Arial Unicode MS

• Specified Open Sans, which is used in the Appian UI

• Removed the <style> tag entirely to check whether CSS was the cause

My questions are:

1. Does this plug-in support Japanese / CJK / Unicode characters when converting HTML to PDF?

2. Is there any way to specify or embed a Japanese font for the PDF conversion?

3. Does the plug-in support @font-face or base64-embedded fonts?

4. Are there any recommended settings or workarounds for generating Japanese PDF files?

5. If this plug-in does not support Japanese text, is there another recommended Appian plug-in or approach for generating PDFs with Japanese content?

Any guidance would be greatly appreciated.

Thank you.
