Alternative to do what job?

It isn't? then what is this about:
This function obeys the conventions for collation order in your
locale settings. For example, punctuation and whitespace characters
might be considered less significant for sorting:
(sort '("11" "12" "1 1" "1 2" "1.1" "1.2") 'string-collate-lessp)
=> ("11" "1 1" "1.1" "12" "1 2" "1.2")
[...]
To emulate Unicode-compliant collation on MS-Windows systems,
bind ‘w32-collate-ignore-punctuation’ to a non-nil value, since
the codeset part of the locale cannot be "UTF-8" on MS-Windows.
The ELisp manual says in addition:
This behavior is system-dependent; e.g., punctuation and whitespace
are never ignored on Cygwin, regardless of locale.
If this doesn't have a big WARNING sign near it, then what would?
