The good news is that all the wills, administrations and inventories of East (Archdeaconry of Lewes +peculiars) and West Sussex (Archdeaconry of Chichester + peculiars) have now been digitized and are available with an Ancestry subscription (or at your local library)....the bad point is the transcription is to the usual Ancestry standard, which is OKish to terrible ..or laughable depending on your mood
These are the most often misunderstood letters (or letter combinations) that I have so far come across:
1. lower case es being mistaken for os (very very common pre 1800)
2. Upper case Cs being mistaken for Gs or Os.
3. Upper case Gs being mistaken for Cs or Ss.
4. Upper case Is being mistaken for Js.
5. Upper case Js being mistaken for Ts.
6. lower case ss being mistaken for rs and vice versa.
7. lower case hs being mistaken for ss or ps in older writing.
8. Upper cases Fs (written ff or Ff) being mistaken for Hs or If or Is.
9. St being mistaken for H.
10. lower case cs being mistaken for rs or ts.
So.... apparently there are 39 Wooks, Wookes, and Wookers - actually Weeks and Weekes

Also the person recorded for the probates of wills is often the executor not the person whose will it was, but again, hopefully the correct(ish) name will be recorded from the cover page or start of the will.
If you are going back to early 1600s or 16th century handwriting most bets are off and the names are often completely mangled. As I suggest with the Prerogative Court wills, for which I suggest using the National Archives index as the primary search, before attempting to find on Ancestry, I would suggest using the East Sussex and West Sussex online catalogues to find if what you want may exist, and then using whatever combination of wildcards or browsing on Ancestry to find where it is
(to find just wills on the archives, search for a name or place and probate)
