I believe the answer is:

aitch

I'm a little stuck... Click here to teach me more about this clue!

'character' is the definition.
(the spelled out name of the letter H)

I can't explain the remainder of the clue.

(Other definitions for aitch that I've seen before include "that I will immediately succeed" , "bone" , "first bit of hymn?" , "character leading heroes" , "Letter sound that's often dropped?" .)

I've seen this clue in The Daily Express and The Mirror.
