I have a customer in France who uses French accents in his address. The lines with the accents don't show up on the admin order form - just a blank line.

When I go into the database and change é to e (for example) the address line shows up on the order form.

My database uses utf8, and the encoding of my zen cart admin page is also utf8:

Table: orders
customers_street_address varchar(64) utf8_unicode_ci

Any ideas what is causing this? I had a customer use Chinese characters for a shipping address and they showed up correctly.
