Kelly H Wilkerson created FOP-2977:
--------------------------------------
Summary: Array index out of bounds with glyph position adjustments
and surrogate pairs
Key: FOP-2977
URL: https://issues.apache.org/jira/browse/FOP-2977
Project: FOP
Issue Type: Bug
Components: renderer/pdf
Affects Versions: trunk
Environment: Windows 10
Reporter: Kelly H Wilkerson
Attachments: arrayindex.patch, input.fo
Out of bounds happens in org.apache.fop.fonts.GlyphMapping.processWordMapping
when:
# There are glyph position adjustments for the font being used
# There are surrogate pairs in the text that has adjustments
The font I've used to reproduce the issue so far is Segoe UI Emoji, which
should be installed on Windows 10 by default.
input.fo attached to cause the crash.
I believe I've fixed the crash in the attached patch.
There's a separate issue demonstrated in the input.fo that the glyphs don't
render in some cases, even though the font is the same throughout everything.
But I'd like to make sure my fix for the crash is correct before I dig into the
rendering issue.
