This snippet:
[<0026>-2<0052004F00520050>-3<0045004C004400B6>5<00560003>] TJ
translates to "Columbia's" in a PDF viewer. That text is in font "/F4" which is described as:
26 0 obj<</Type/Font/DescendantFonts[27 0 R]/ToUnicode 31 0 R/BaseFont/Times#20New#20Roman/Subtype/Type0/Encoding/Identity-H>>
That in turn refers to a compressed unicode mapping table in object 31. Alas, CAM::PDF does not support mapping tables (I didn't even know they existed until now!)
