> [PATCH] 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: 2.6
> Environment: Windows 10
> Reporter: Kelly H Wilkerson
> Assignee: Simon Steiner
> Priority: Minor
> Fix For: trunk
>
> Attachments: arrayindex.patch, drawTextWithDX.patch, fop.xconf,
> input.fo, test.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.
