This is described in perlunicode(1).
IIRC as of 5.6 locales were activated by calling
  use locale;
  setlocale(LC_ALL, "");

In 5.8, Perl internally uses Unicode characters.  When user is in a
UTF-8 locale, Perl assumes that input and output are UTF-8 encoded;
otherwise previous behavior occurs.
As wml::fmt::isolatin contains latin1 characters, Perl should complain
that some characters are invalid.  But it complains only when those
characters are used, and not read.

I could fix WML, but it will then require perl 5.8; and as Perl
interaction with UTF-8 locales will change in 5.8.1, I am quite
reluctant to perform this change now.

A trivial workaround is to rename wml into wml.real and create a
simple shell script like:
  #! /bin/sh
  LC_ALL=C
  LANG=C
  unset LANGUAGE
  export LC_ALL LANG
  wml.real "$@"

BTW are you sure you need to call wml::fmt::isolatin?  It is pretty
useless nowadays.
