Hua Lan commented on FOP-2491:

With the fixed OTFSubSetFile class, I have another issue when using the 
I tested the string "new font, new world" in different languages. 

For Simplified Chinese("新字体,新世界"):
the character '界' is not vertically aligned with the other characters in the 
same line. 

For Traditional Chinese("新字體,新世界"):
it pops up with the message "Cannot extract the embedded font 
'EAAAAXX+NotoSansCJKTC'" and it doesn't generate the correct output.

For Japanese('新しいフォント、新しい世界'):
the character '新' and '界' are not vertically aligned with the other characters 
in the same line.

For Korean('새 글꼴 , 새로운 세계'):
it generates the correct output.

>                 Key: FOP-2491
>                 URL: https://issues.apache.org/jira/browse/FOP-2491
>             Project: FOP
>          Issue Type: Bug
>    Affects Versions: 2.0
>         Environment: FOP: 2.0
> Open Font: Noto-Sans Cjk 
> (https://noto-website.storage.googleapis.com/pkgs/NotoSansCJKTC-hinted.zip)
>            Reporter: Leo Yang
>         Attachments: after.pdf, before.pdf, fop.xconf, svnSubset.patch, 
> test.fo
> 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.
