(It’s not the fastest thing in the world, but it does help +in some circumstances.) +<p>However, there is a problem: the viewer wants to look at Unicode text, +but no ordinary TeX-based system deals in Unicode text. +Fortunately for us Anglophones, this is is hardly ever a problem for +our text, since even Knuth’s “OT1” encoding matches ASCII (and hence +the lowest 128 characters of Unicode) for most things printable. +However, using the inflected characters of Continental European +languages, or anything that doesn’t use a Latin alphabet, there is +potential for problems, since TeX’s view of what a font is doesn’t +map PDF’s and the reader won’t understand... +<p>... Unless you use the <i>cmap</i> package with PDFLaTeX, +that is. The package will instruct PDFTeX to load character +maps into your PDF for output fonts encoded according to the T1 +(Western European Languages), T2A, T2B, or T2C (Cyrillic Languages), +or T5 (Vietnamese) encodings. If your document uses such encodings, +viewers that can search will use the maps to interpret what they find +in the file. +<p>Unfortunately, the package only works with fonts that are directly +encoded, such as the <i>cm-super</i> distribution. Fonts like Adobe +Times Roman (which are encoded for (La)TeX use via virtual fonts) +are not amenable to this treatment. +<dl> +<dt><tt><i>cmap.sty</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/cmap.zip">macros/latex/contrib/cmap</a> (<a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/cmap.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/macros/latex/contrib/cmap/">browse</a>) +<dt><tt><i>cm-super fonts</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/fonts/ps-type1/cm-super.zip">fonts/ps-type1/cm-super</a> (<a href="ftp://cam.ctan.org/tex-archive/fonts/ps-type1/cm-super.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/fonts/ps-type1/cm-super/">browse</a>) +</dl> +<p> +<p><p><p><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=srchpdf">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=srchpdf</a> +</body> |
