To fully support any language having characters outside
AdobeStandard encoding(s), one has to set ToUnicode CMap font
resource (see section 5.9 of
http://partners.adobe.com/asn/developer/acrosdk/docs/filefmtspecs/PDFReference.pdf).

Providing CMaps ensures operations as searching, indexing, and
exporting of text to other applications.
ToUnicode entry is in PDF since 1.2 (Acrobat 3).

For details see http://partners.adobe.com/asn/developer/pdfs/tn/5411.ToUnicode.pdf (Adobe Technical Note #5411 ToUnicode Mapping File
Tutorial).
