Single quote breaks autocomplete

[bekok]

In the remote datasource demo of jQuery UI autocomplete any entry with a single quote (') prevents autocomplete from working. Examples are "Cetti's Warbler", "Eleonara's Falcon", "Pallas's Leaf Warbler", "Ross's Goose", "Pallas' Bunting", "Marmora's Warbler", "Ménétries's Warbler", "Rüppel's Warbler", "Ross's Gull", "Bulwer's Petrel", "Naumann's Thrush", and "Heuglin's Gull".

The autocomplete works again whenever a string is found that doesn't include the single quote. For example, if you search for "Ross" (from Ross's Goose) nothing is found, but if you search for "Rossb" you will get option like "Common Crossbill"

This has been tested on Mac Os X 10.7 with Firefox 12.0 and Chrome 18.0.
