cmap – Make PDF files search­able and copy­able

The cmap pack­age pro­vides char­ac­ter map ta­bles, which make PDF files gen­er­ated by pdfLaTeX both search­able and copy-able in ac­ro­bat reader and other com­pli­ant PDF view­ers. En­cod­ings sup­ported are OT1, T1, T2A, T2B, T2C and T5, to­gether with LAE (Ara­bic), LFE (Farsi) and LGR (Greek) and a vari­ant OT1tt for cmtt-like fonts.
The pack­age’s main lim­i­ta­tion cur­rently is the in­abil­ity to work with vir­tual fonts, be­cause of lim­i­ta­tions of pdfTeX. This re­stric­tion may be re­solved in a fu­ture ver­sion of pdfTeX.
