Subject: [PATCH] Doc: fix some rendering problems in the PDF docs build.

Tweak column widths in a couple of tables to avoid "contents
... exceed the available area" warnings.  Remove usage of
some non-Latin-1 characters.

            Full normalization is important in some cases, such as when
-           multiple accents are applied to a single character. For instance,
-           <literal>'ệ'</literal> can be composed of code points
-           <literal>U&amp;'\0065\0323\0302'</literal> or
-           <literal>U&amp;'\0065\0302\0323'</literal>. With full normalization
+           multiple accents are applied to a single character. For example,
+           the code point sequences <literal>U&amp;'\0065\0323\0302'</literal>
+           and <literal>U&amp;'\0065\0302\0323'</literal> represent
+           an <literal>e</literal> with circumflex and dot-below accents
+           applied in different orders. With full normalization
            on, these code point sequences are treated as equal; otherwise they
            are unequal.
