I seem to have an issue with users who copy-paste their usernames and
passwords coping and pasting leading and trailing space characters.
The obvious fix was to trim() the values that I receive, but I worry
how that would affect users who use a space at the beginning or end of
their password. Of course, if I trim() also when the user is setting
his password then he will never know that his password is really 1
digit shorter, but do I really want to do that? Thoughts? Thanks!

Can't you simply specify the allowed characters that can be used for PWs and usernames?

I always do, e.g., 6-8, case sensitive, alphanumerics, and the following characters: "@, #, $, %, &, *, -".

Then, I trim() and check the submitted PW for any exceptions to the rules.
