Subject [jira] [Commented] (PDFBOX-4469) Exception in thread "main" java.io.EOFException when load a TTF file
Date Thu, 21 Feb 2019 17:48:00 GMT

    [ https://issues.apache.org/jira/browse/PDFBOX-4469?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16774350#comment-16774350

Tilman Hausherr commented on PDFBOX-4469:
-----------------------------------------

PDFBox needs the GSUB segment for vertical usage (PDFBOX-4106). I don't want to change PDFBox
for a broken font. If bold simsun is used frequently in China, then you should be able to
find it (I couldn't, but I searched only in english), or better: buy it.

What you could do is to disable the broken segment:
 - open your font in a hex editor
 - go to offset 13918067
 - change 01 into 00
 - save

Alternatively (if you want to create PDFs), use the normal SimSun font, and simulate bold
by using {{contentStream.setRenderingMode(RenderingMode.FILL_STROKE)}}.

It might also be possible to fix the problem with FontForge, but I didn't try it, their UI
is terrible. DTL OTMaster 3.7 light can open the font, and the GSUB script list part is a
complete mess (which confirmed to me that it isn't a PDFBox bug), but that version can't save.
(but it is a very nice tool)
