Blob with special character in filename

Hello,

We are facing issues with Blob assets having special character in filename such as © copyright symbol.

To reproduce:

1) Create new image asset

2) Upload image file filename having copyright symbol. For example "Paresh testing image having special character in filename©.jpeg"

3) It gets uploaded and save correctly.

4) Mungoblobs table has correct data. See below

Executing: select * from mungoblobs where URLData like '%Paresh%'

ID	HASHVALUE	REFCOUNT	URLDATA	FOLDERVALUE	FILEVALUE
1408032028843	177754282	1	498/1005/Paresh testing image having special character in filename©.jpeg	498/1005	Paresh testing image having special character in filename©.jpeg

Total RowCount: 1
