On my server it returns 0 rows, so it appears like some other things affect this. Maybe default collation. Probably.
I'd suspect a different set of Extended ASCII characters, probably not the default collation on the server. For the folks who are getting no records back, what language is the machine running?
[appending] Yeah, it looks like several of the ASCII character sets don't include those AE/ae characters. http://en.wikipedia.org/wiki/ISO/IEC_8859
