A simple font without a usable /ToUnicode reads its text from glyph names, and a name missing from the glyph list dropped the glyph from the extracted text while the page still drew. An 821-page book set in Type1C fonts named C39, C40, ... extracted 4 KB of front matter and nothing else. - glyph_name_to_text applies the Adobe Glyph List Specification's full mapping: drop from the first '.', split on '_', map each component through the list or as uniXXXX / uXXXX. f_i, f_l and hyphen.case now read as fi, fl and '-'. Type 1, CFF, standard and embedded TrueType simple fonts use it. - A Type 1 / CFF / standard font name that only numbers the glyph (one or two letters then digits, ZapfDingbats' aN excepted) reads as the code's StandardEncoding character, so C174 is the fi ligature and C208 an em dash. The book now extracts 1.9 MB (pdftotext: 1.85 MB), with fi and em dashes where pdftotext writes Latin-1 mojibake.
