Jesper on "[Plugin: Contact Form 7] File upload, × instead of x"

Hi.
I really love this plugin and use it in several websites.
I just stumbled up on a problem though. I use the upload function, and in the email that comes to me, i have posted an url+the file name, so i get a clickable link to the uploaded file. Though when the filename contains a number and x-sign, the x-sign converts to × (multiplication sign) in the mail. This makes the link broken. Example "mydomain.com/uploads/example-100x100" becomes "mydomain.com/uploads/example-100×100". Does anyone know what seems to be happening here?
Basically my normal x gets replaced by (http://www.fileformat.info/info/unicode/char/d7/index.htm).
Thanks guys!
