What does the "CMap/encoding Identity-H" tell us? the character codes (CIDs) are the same as the glyph indices (GIDs), so there's no need to remap them.

to start the extract of text, use:
node pdf2json -cvf ill01.pdfI expect true character mappings if there are UTF-8 characters encoded, see at end for details. See extracted text of ill01.pdf See extracted text of ill00.pdf and search for terms that include 'ff' ot 'ft' or "n's"
ill01.pdf PDF file(s) that cause the issue. See top: ill01.pdf

What does the "CMap/encoding Identity-H" tell us? the character codes (CIDs) are the same as the glyph indices (GIDs), so there's no need to remap them.
However, without a ToUnicode CMap, PDF viewers can't map glyphs to Unicode values.
