-Interactively, prompts for a Unicode character name or a hex number
-using `read-char-by-name'.
+Interactively, prompt for CHARACTER.  You can specify CHARACTER in one
+of these ways:
 
-You can type a few of the first letters of the Unicode name and
-use completion.  If you type a substring of the Unicode name
-preceded by an asterisk `*' and use completion, it will show all
-the characters whose names include that substring, not necessarily
-at the beginning of the name.
+ - As its Unicode character name, e.g. \"LATIN SMALL LETTER A\".
+   Completion is available; if you type a substring of the name
+   preceded by an asterisk `*', Emacs shows all names which include
+   that substring, not necessarily at the beginning of the name.
 
-This function also accepts a hexadecimal number of Unicode code
-point or a number in hash notation, e.g. #o21430 for octal,
-#x2318 for hex, or #10r8984 for decimal.
+ - As a hexadecimal code point, e.g. 263A.  Note that code points in
+   Emacs are equivalent to Unicode up to 10FFFF (which is the limit of
+   the Unicode code space).
 
-Point, and before-insertion markers, are relocated as in the function `insert'.
-The optional third arg INHERIT, if non-nil, says to inherit text properties
-from adjoining text, if those properties are sticky.  If called
-interactively, INHERIT is t.  */)
+ - As a code point with a radix specified with #, e.g. #o21430
+   (octal), #x2318 (hex), or #10r8984 (decimal).
+
+If called interactively, COUNT is given by the prefix argument.  If
+omitted or nil, it defaults to 1.
+
+Inserting the character(s) relocates point and before-insertion
+markers in the same ways as the function `insert'.
+
+The optional third argument INHERIT, if non-nil, says to inherit text
+properties from adjoining text, if those properties are sticky.  If
+called interactively, INHERIT is t.  */)
