Jonck van der Kogel commented on PDFBOX-139:
--------------------------------------------

Does anyone know of a work-around for the time being? This bug is really annoying.

> In fact the cause of this exception is that the 
> CMapParser does not recognize the begincidchar and 
> begincidrange operators (in the case of the 90ms-RKSJ-
> H) encoding and usecmap operator in the case of 
> Identity-V encoding.
> The cmap files for these encodings are not properly 
> parsed and the corresponding Cmap objects do not 
> contain neither one nor two byte mappings, further the 
> lookup() method returns null.
> I'll attach two samples for the 90ms-RKSJ-H encoding 
> and one for the Identity-V encoding.
> I'll attach cmap reference also.
