removing undefined return character

[news.telenet.be]

I have an access database which is converted from filemaker on macintosh. In
some fields at the end of the field I have some characters acting like
returns, but I don't know what they are. I want to delete them by replacing
them with nothing or with an update query but access doesn't seem to find
the characters. Is there a way to find those characters and replace them
with nothing. I want to trim the fields so they're gone. Whenever I try to
make a report they are very annoying.

Thanks in advance.
