> Extracts entire file content for ASCII DXF files

> Key: TIKA-1817
> URL: https://issues.apache.org/jira/browse/TIKA-1817
> Project: Tika
> Issue Type: Bug
> Affects Versions: 1.11
> Reporter: Zoltan Toth
> Attachments: jcsample-screendump.jpg, jcsample.dxf
>
>
> By definition, ASCII DXF files are encoded in plain text. However. the vast
> majority of their content is not intended to be human readable (see
> https://en.wikipedia.org/wiki/AutoCAD_DXF). Unfortunately for these files,
> Tika simply "extracts" the entire content of the file instead of the
> human-readable portions (i.e. comments etc.) that a CAD tool would render.
> This results in massive amounts of rubbish data being returned with dire
> consequences for applications that rely on this.
> It would be nice if only the human-readable text fields were extracted.
> Failing this, it would still be nice if no text was extracted from these
> files at all.
