The main purpose is to make ligatures and some other glyphs like smallcap letters or oldstyle digits from OpenType fonts searchable. This patch also contains a minor fix that allows use of fonts without embedding, for example MinionPro or MyriadPro (which are distributed with Acrobat Reader >= 7.0 but from their use is restricted with Acrobat Reader only). How to apply: ~~~~~~~~~~~~~ - this patch applies to the pristine pdftex-1.40.0-beta-20060213 sources only; if you have applied another patch(es) to the sources, please discard them and start from the fresh ones. - how to apply: ,-------- | cd /path/to/pdftex-1.40.0-beta-20060213/src | cat /path/to/the/patch | patch -p1 | ./configure | cd texk/web2c | make pdfetex `-------- If you want to be careful, try the patch with the option '--dry-run' first to see whether the patch can be applied without problems. Usage: ~~~~~~ add the following lines into your document, somewhere at the beginning: ,-------- | \input glyphtounicode.tex | \pdfgentounicode=1 `-------- Customization: ~~~~~~~~~~~~~ If pdftex cannot generate the right ToUnicode value for some glyphs (probably because the glyph name is not ``known'' to pdftex), it's possible to add further entries so pdftex can learn how to generate unicode for such ``unknown'' glyphs. The syntax is simple: \pdfglyphtounicode{<glyph-name>}{<unicode-value>} Example: \pdfglyphtounicode{A}{0041} says that glyph 'A' has its unicode U+0041 The entries in glyphtounicode.tex cover Adobe Glyph List (glyphlist.txt version 2.0) and some addtional glyphs (texglyphlist.txt version 2.33, coming from from lcdf-typetools), plus some additional entries for ligatures. If some glyph name cannot be found, pdftex does some simple name translations: - remove any ".xxx" suffix from glyph name, where "xxx" is a string consisting of alphabetic characters. For example "A.sc" => "A" - remove suffix like "small", "oldstyle", "inferior" and "superior" from glyph name. For example "Asmall" => "A" The result name then is looked up again to find a unicode. Ligatures require a special form of ToUnicode. Example: \pdfglyphtounicode{ff}{00660066} here '0066' is the unicode string for 'f'. Some ligatures have their name like 'f_f_i', in such case the command should be \pdfglyphtounicode{f_f_i}{006600660069} ie '_' is removed from the glyph name, and then all letters are translated to their unicode string. ----------------------------------------------------------------------
