Archimedes Trajano commented on PDFBOX-3903:
--------------------------------------------

Since FOP-2734 is for FOP, I am attaching the details of what I did and where I suspect it
is a PDFBOX issue here.  (I can't attach files so here's the gist [https://gist.github.com/trajano/8b1f4b5f961e867e6c78b581dba0ca72)]

 

I use OpenHtmlToPDF but it yielded similar output to FOP-2734.  I do use Noto Fonts and I
can tell some of it are working namely the CJK, but some are not namely Khmer and Emoji. 
These two lines

  .useFont(() -> Thread.currentThread().getContextClassLoader().getResourceAsStream("fonts/NotoColorEmoji.ttf"),
"noto")
  .useFont(() -> Thread.currentThread().getContextClassLoader().getResourceAsStream("fonts/NotoEmoji-Regular.ttf"),
"noto")

 

I tried to switch in and out to see if emojis work. but they didn't.  However

  .useFont(() -> Thread.currentThread().getContextClassLoader().getResourceAsStream("fonts/NotoSansKhmer-Regular.ttf"),
"noto")

Do not render either.

As I noted in the other bug

 

14:23:24.631 [main] DEBUG org.apache.fontbox.ttf.GlyphSubstitutionTable - Type 3 GSUB lookup
table is not supported and will be ignored
 14:23:24.631 [main] DEBUG org.apache.fontbox.ttf.GlyphSubstitutionTable - Type 4 GSUB lookup
table is not supported and will be ignored
 14:23:24.631 [main] DEBUG org.apache.fontbox.ttf.GlyphSubstitutionTable - Type 6 GSUB lookup
table is not supported and will be ignored
 14:23:24.632 [main] DEBUG org.apache.fontbox.ttf.GlyphSubstitutionTable - Type 7 GSUB lookup
table is not supported and will be ignored

 

Probably indicates that the characters I am using are not supported yet.  However, what I
provided may be a good unit test to add to the harness.
