@code{?\u@var{xxxx}} and @code{?\U@var{xxxxxxxx}} represent code
points @var{xxxx} and @var{xxxxxxxx}, respectively, where each @var{x}
is a single hexadecimal digit. For example, @code{?\N@{U+E0@}},
-@code{?\u00e0} and @code{?\U000000E0} are all equivalent to @code{?à}
-and to @samp{?\N@{LATIN SMALL LETTER A WITH GRAVE@}}. The Unicode
-Standard defines code points only up to @samp{U+@var{10ffff}}, so if
-you specify a code point higher than that, Emacs signals an error.

You can specify characters by their hexadecimal character
codes. A hexadecimal escape sequence consists of a backslash,
@samp{x}, and the hexadecimal character code. Thus, @samp{?\x41} is
the character @kbd{A}, @samp{?\x1} is the character @kbd{C-a}, and
-@code{?\xe0} is the character @kbd{à} (@kbd{a} with grave accent).
-You can use any number of hex digits, so you can represent any
-character code in this way.
+@code{?\xe0} is the character @kbd{@`a} (@kbd{a} with grave accent).
+You can use one or more hex digits after @samp{x}, so you can
+represent any character code in this way.
