New Registration input fields allow characters that causes exporting to excel spreadsheets to fail on queries

The input fields for new customer registrations accept characters that excel spreadsheets cannot not read that causes exporting queries to excel spreadsheet to fail with an unrecognized character in field error.

Solution would be to validate registration fields to exclude characters that will cause excel spreadsheet to fail.

To Duplicate:

1. Create a new customer and fill in all the fields.

2. In the company field type in the following: Berlin "Hospital"   (with Hospital in quotes)

3. From the admin panel do a search on all customers and then publish it to excel spreadsheet.  The spreadsheet creation will fail because of the quotation marks around the word "Hospital"
