[jira] [Commented] (PDFBOX-1397) Some characters are displayed by default font (not by correct font)

    [ https://issues.apache.org/jira/browse/PDFBOX-1397?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13442352#comment-13442352 ] 

Juraj Lonc commented on PDFBOX-1397:
------------------------------------

It seems that embedded font does not contain "cmap" table (it is defined in pdf object instead). JRE is not able to process such font and automatically makes substitution.

Do you think this would be a good solution?
1. extract that embedded font
2. process "cmap" defined in pdf object
3. make copy of that font with cmap included
4. replace font's object stream in pdf

so JRE would get font that is correct.
