> URL: https://issues.apache.org/jira/browse/PDFBOX-2721
> Project: PDFBox
> Issue Type: Bug
> Components: FontBox
> Affects Versions: 2.0.0
> Reporter: Juraj Lonc

> Attached PDF file works fine in Adobe Reader, but PDFBox logs warnings:
> 2015-03-20 15:48:57,573 WARN [org.apache.pdfbox.pdmodel.font.PDFont]
> (http-0.0.0.0-8080-7) Invalid ToUnicode CMap in font HPDFAA+Thoth-Unicode
> It seems that you require "beginbfchar" or "beginbfrange" in CMap. But should
> it be required?
> CMap definition contains "beginnotdefrange" and this is ignored in PDFBox.
> PDF Reference says:
> beginnotdefchar, endnotdefchar, beginnotdefrange, and endnotdefrange
> define notdef mappings from character codes to CIDs. As described in the
> section “Handling Undefined Characters” on page 355, a notdef mapping is
> used if the normal mapping produces a CID for which no glyph is present in
> the associated CIDFont.
