Description

Symptom: Based on FOP 2.0 release, the open-type font can be embedded into PDF document, however, based on the testing with FOP 2.0, the google-noto-sans-Cjk font cannot be embedded into PDF document.

How to repeat:
1. Get FOP 2.0 library.
2. Get Google-Noto-Sans from https://noto-website.storage.googleapis.com/pkgs/NotoSansCJKTC-hinted.zip.
3. Set the fop.xconf as following:
<font embed-url="file:///C:/Font/NotoSans.otf" embedding-mode="subset">
<font-triplet name="Noto Sans CJK TC Regular" style="normal" weight="normal"/>
</font>
4. Set the FOP as following:
<?xml version="1.0" encoding="UTF-8"?>
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
<fo:layout-master-set>
<fo:simple-page-master margin="2cm" page-width="21.0cm" page-height="29.7cm" master-name="A4-portrait">
<fo:region-body/>
</fo:simple-page-master>
</fo:layout-master-set>
<fo:page-sequence master-reference="A4-portrait">
<fo:flow flow-name="xsl-region-body">
<fo:block font-family="Noto Sans CJK TC Regular">Hello Noto-OTF!</fo:block>
</fo:flow>
</fo:page-sequence>
</fo:root>
5. Generate the PDF, there is no error reported.
6. Open the PDF file in Acro-Reader, it will report the "cannot extract the embedded font" error.
