[jira] [Commented] (PDFBOX-5806) Wrong font substitution for Wingdings
[ https://issues.apache.org/jira/browse/PDFBOX-5806?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17838443#comment-17838443 ]
Tilman Hausherr commented on PDFBOX-5806:
-----------------------------------------
This change may have to be limited to WingDings (and maybe Symbol) because it would mean that other fonts won't be replaced with a bold font where it makes sense. I got several rendering changes that I'll analyse later.
