[jira] [Commented] (PDFBOX-5162) Text extraction lost

["Tilman Hausherr (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-5162?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17318530#comment-17318530 ] 

Tilman Hausherr commented on PDFBOX-5162:
-----------------------------------------

It is somehow related to this segment in PDFont.java
{code}
// due to the conversion to an int it is no longer possible to determine
// if the code is based on a one or two byte value. We should consider to
// refactor that part of the code.
// However simple fonts with an encoding are using one byte codes so that
// we can limit the CMap mappings to one byte codes by passing the origin length
{code}
This is from PDFBOX-4749. In this file, the ToUnicode stream has 2 bytes. Calling {{toUnicodeCMap.toUnicode(code)}} works, but then the text extraction tests fail.
Btw Adobe Reader is not able to do a text extraction.
