Hi, when doing text extraction, we sometimes get the warning "[CmapSubtable] Format 14 cmap table is not supported and will be ignored". The code in org.apache.fontbox.ttf.CmapSubtable mentions that this format is for "Unicode Variation Sequences". A comment in the source code links a blog entry (which now seems to be available at https://ccjktype.fonts.adobe.com/2013/05/opentype-cmap-table-ramblings.html instead).
I was not able to find anything about format 14 cmap tables in the PDFBox issue tracker. Is support for those kinds of tables planned for future versions of PDFBox?
