Pity ;-(. It also looks as if loading manually a cmap isn't an option either (if \pdfgentounicode is 1) as \pdfnobuiltintounicode is not support either. And I didn't find yet examples or a documentation how to define a callback that "decorates" the tfm. -- Ulrike Fischer http://www.troubleshooting-tex.de/ _______________________________________________ dev-luatex mailing list -- [email protected] To unsubscribe send an email to [email protected]
