Not as much as film. While silicon CCD chips do have some small
sensitivity to longer end of UV spectrum, the glass used in lens, and
the color filters further restrict the UV response of a digicam.
There have been some special CCD chips made with enhanced UV response.
Some are GaAs chips, others silicon with care taken not to loose what
small UV response silicon already has.
In general, though, digicams with silicon CCDs are not that good for
doing UV photography. Better to use fast film and scan film afterwards.
One technique which could be done is to use an image converter, a
flourescing screen sensitive to UV, with the silicon CCD chip imaged on
the screen.
BTW, Canon used to sell a lens specially made for enhanced UV
transmittance. The glass in the lenses on most cameras limits the UV
response more than the film. Actually, film is even sensitive to X-ray,
but the lenses will not refract and image X-rays.
