I'm looking to validate the length of a textarea using a regular expression validator. It should allow all characters and crlfs.

Also, I'm saving to a mix of varchar and nvarchar fields in MSSQL, do I need to be concerned about the way crlfs are saved there? I'm in a hurry to do this right, so I'll be researching all this on my own but I'm just hoping someone out there might have experience handling such concerns.
