+<h3>Searching PDF files</h3>
+<p/>In principle, you can search a PDF file: the text of the file
+is available to the viewer, and at least some viewers provide a search
+facility. (It&rsquo;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&rsquo;s &ldquo;OT1&rdquo; 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&rsquo;t use a Latin alphabet, there is
+potential for problems, since TeX&rsquo;s view of what a font is doesn&rsquo;t
+map PDF&rsquo;s and the reader won&rsquo;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.
