I believe that current version of glyphtounicode.tex is here: https://foundry.supelec.fr/scm/viewvc.php/branches/stable/source/texmf/tex/generic/pdftex/glyphtounicode.tex?view=markup&root=pdftex I found out that glyph Delta is not specified correctly and also in above file. There is \pdfglyphtounicode{Delta}{2206}. But Delta (as greek capital letter) has unicode 0394. Code 2206 is for increment and that already has correct definition: \pdfglyphtounicode{increment}{2206} -- Pali Rohár pali.rohar@gmail.com
