Currently I am passing the JavaScript array:

 

collection = ['David', 'Dean', 'Dickson', '詹姆斯', 'Larry', 'Dan', 'Davy', 'Zoro', 'Scott', 'Ave', 'Street', 'Parade'];

 

When I type 'd' is dropping down the correct items :D But when I type 詹 (chinese) it does not drop down the item '詹姆斯'. How can I add utf-8 characters to be accepted as input searches?

 

Also how can I change the behaviour of appending a ',' to accept spaces so that I could type the address '24 River Ave' into a text box and get two autocomplete drop downs (River and Ave)?

 

Help is much appreciated :D
