--- Comment #4 from Glenn Adams <gad...@apache.org> --- Created attachment 29090 --> https://issues.apache.org/bugzilla/attachment.cgi?id=29090&action=edit test FO file showing gsub/gpos application This FO shows the same data with Angsana UPC with various settings of language and script. Note that with or without language='dflt' and with or without script='thai' does not impact the results. However, specifying language='th' does prevent gsub/gpos application. -- You are receiving this mail because: You are the assignee for the bug.
