Let me just quote a bit:
Austen gave nine presentation copies of Emma to family, one to the library of the Prince Regent and one to a countess.
Ms Sharp's was the only one given to a personal friend - a demonstration of the bond between the two women.
They became friends while Ms Sharp was working as governess to the author's brother Edward, and remained close for many years.
For the novel, Austen created a governess character called Miss Taylor.
Set in Regency England, the novel's heroine, a young woman aged 21, is described in the opening paragraph as "handsome, clever and rich", but also "slightly spoiled".
Don't worry about the book or Anne Sharp or anything for a minute.
This is Emma's entire opening paragraph.
EMMA WOODHOUSE, handsome, clever, and rich, with a comfortable home and happy disposition, seemed to unite some of the best blessings of existence; and had lived nearly twenty-one years in the world with very little to distress or vex her.
Trying to be fair I checked the rest of the first page and a bit, until the topic changes. Funnily, no trace of 'slightly spoiled' there either.
I thought: hmmm, where do journalists (and press release writers) go when they want some random yet marginally relevant words with which to pad out their articles?
Wikipedia's page on Emma says, under the subheading 'Principal Characters':
Emma Woodhouse, the protagonist of the story, is a beautiful, high-spirited, intellectual, and 'slightly' spoiled woman of almost 21.
At least the Wiki kids managed to get her age right. 'Intellectual'? - well, I suppose to them Emma seems like a bit of an egghead. I don't know why 'slightly' appears in quotation marks like that. It's not a quotation.
Stuff like this makes me sad for the BBC, of whom it's not unreasonable to expect better.
