A digital character (3,5)
I believe the answer is:
tom thumb
'a digital character' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
This is all the clue.
Can you help me to learn more?
(Other definitions for tom thumb that I've seen before include "Tiny child of fairy tale" , "Notably small person" , "Small hero" , "Diminutive character of English folklore" , "Tiny hero of nursery tale - digital?" .)
