> Key: FOP-2638
> URL: https://issues.apache.org/jira/browse/FOP-2638
> Project: FOP
> Issue Type: Bug
> Components: fo/block, layout/unqualified
> Affects Versions: trunk
> Environment: Operating System: All
> Platform: All
> Reporter: Simone Rondelli
>
> In {{GlyphMapping.processWordMapping}} the script of the text is retrieved
> using {{String script = text.getScript()}}.
> If the script returned is not listed in the Font then then gsub/gpos
> features will be ignored even if applicable.
> h5. Example:
> The font [EmojiOne|https://github.com/eosrei/emojione-color-font] is a font
> for Emoji and contains a Ligatures table for _latn_ script. Thsi is what
> happen when FOText.getScript is called:
> * ๐ฎ๐น๐จโ๐จโ๐ฆ (Only emoji) -> script = 'zyyy'
> * test๐ฎ๐น๐จโ๐จโ๐ฆ (Latin + Emoji) -> script = 'auto'
> * ๅ
็งฆๅ
ฉๆผข๐ฎ๐น๐จโ๐จโ๐ฆ (Chinese + Emoji) -> script = 'auto'
> In all these cases ApacheFOP is not able to apply the ligature table.
> h5.Acceptance Criteria
> Ensure ApacheFOP reads the gsub/gpos table even if the script recognized for
> the text differs from the one defined in the font.
