using grep to find filenames with accented characters or ñ in the search term
===

I'm trying unsuccessfully to use (e)grep to list files in a directory when my search term includes Spanish characters such as accented vowels or "ñ" (e.g. bebé, caña). In the case of accented vowels, if I use the unaccented vowel, the search works as in the following:

    $ ls | egrep 'bebe'
    8 bebé
    IMQ_bebé1.wav
    IMQ_bebé2.wav
    IMQ_bebé3.wav
    IMQ_bebé4.wav
    IMQ_bebé5.wav
    IMQ_bebé6.wav

However, if I include the accented vowel in the search term, (e.g. `$ ls | egrep 'bebé'`)
I get nothing.

The reason why using non-accented vowels in the search term is not possible is because this is part of a larger shell script that gets it's search terms from a text file. Also, search terms with "ñ" don't work, nor do they work with just "n". Plus, I'm sure there must be a way to do this!

I'm working on Mac OS X 10.6.8. My locale is as follows:

    $ locale
    LANG="en_CA.UTF-8"
    LC_COLLATE="en_CA.UTF-8"
    LC_CTYPE="en_CA.UTF-8"
    LC_MESSAGES="en_CA.UTF-8"
    LC_MONETARY="en_CA.UTF-8"
    LC_NUMERIC="en_CA.UTF-8"
    LC_TIME="en_CA.UTF-8"
    LC_ALL=
