[jira] [Comment Edited] (FOP-2701) Some of the latin ligatures make text not searchable in PDF

Indeed, the workaround with embedding-mode="full" doesn't work for the fonts
"cambria.ttc" and "Calibri.ttf".
In my project I observed the ligature problem with the font
"FrutigerNeueLTW1G-Light.otf". There the workaround works.
I add the following attachments:
- 3-fonts-fop.xconf
- 3-fonts-latn-ligatures-FOP.fo
- 3-fonts-latn-ligatures-FOP.pdf
- 3-fonts-copy-paste-result.png
Directory structure:
fop/conf/3-fonts-fop.xconf
fop/conf/FrutigerNeueLTW1G-Light.otf
fop/3-fonts-latn-ligatures-FOP.fo
Execute:
cd fop
fop -fo 3-fonts-latn-ligatures-FOP.fo -pdf 3-fonts-latn-ligatures-FOP.pdf -c
conf\3-fonts-fop.xconf
The example compares the ligature problem with three fonts and the embedding
mode "subset" and "full".
In the different fonts the problem happens with different ligatures.
The embedding mode "full" doesn't work with all fonts.
Maybe it depends on the font type or the font itself.
Unfortunatelly I cannot supply the "FrutigerNeueLTW1G-Light.otf" font, since it
is not for free.
Maybe you can get a free licence as a developer.
