Since regexs are generally portable, here is a Perl version that splits
on any non alpha-num including spaces, but disregards the '$'. (regex
between / and /. Even though you said no Perl, I did it anyway ;)

my $string = 'hello%wo$rld*ste ve';

print join (', ', (split(/[^\w\$]/, $string)));

...output:

hello, wo$rld, ste, ve
