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.
