-/*!
-    \brief Generates a url-friendly string representation from \a title.
-
-    "Url-friendly" in this context is a string that contains only a subset of
-    printable ascii characters.
-
-    The subset includes alphanumeric (alnum) characters ([a-zA-Z0-9]), printable
-    ascii characters, space, punctuation characters, and common symbols.
-    Non-alnum characters in this subset are replaced by a single dash. Leading
-    and trailing dashes are removed, such that the resulting string does not
-    start or end with a dash. Any capital character is replaced by its lowercase
-    counterpart.
-
-    If any character in \a title is non-latin, or latin and not found in the
-    aforementioned subset (e.g. 'ß', 'å', or 'ö'), a hash of \a title is
-    appended to the final string.
-
-    Returns a string that is normalized for the purpose of generating fragment
-    identifiers for \a title in URLs.
