For instance, @var{str1} is considered less than @var{str2} if
its first differing character has a smaller numeric value. If
@var{ignore-case} is non-@code{nil}, characters are converted to
-lower-case before comparing them. Unibyte strings are converted to
+upper-case before comparing them. Unibyte strings are converted to
multibyte for comparison (@pxref{Text Representations}), so that a
unibyte string and its conversion to multibyte are always regarded as
equal.
This function works like @code{assoc}, except that @var{key} must be a
string or symbol, and comparison is done using @code{compare-strings}.
Symbols are converted to strings before testing.
-If @var{case-fold} is non-@code{nil}, it ignores case differences.
+If @var{case-fold} is non-@code{nil}, @var{key} and the elements of
+@var{alist} are converted to upper-case before comparison.
Unlike @code{assoc}, this function can also match elements of the alist
that are strings or symbols rather than conses. In particular, @var{alist} can
be a list of strings or symbols rather than an actual alist.
The characters in @var{string}, other than the format specifications,
are copied directly into the output, including their text properties,
