Subject [jira] [Commented] (PDFBOX-3147) PDFBox fail to write Thai character properly
Date Fri, 04 Dec 2015 03:49:11 GMT

    [ https://issues.apache.org/jira/browse/PDFBOX-3147?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15039709#comment-15039709
] 

Nattapong Sirilappanich commented on PDFBOX-3147:
-------------------------------------------------

The leftmost oval in compareresult.jpg issue seem to be better in your file (example.pdf)
The remain issue of that text in oval is the above combining character should be render a
little bit lower. I think there's a glyph in font or some offset define in GPOS or GSUB for
this case.
The other red green oval in compareresult.jpg issue seem to be found in your file as well.
