The first letter of a sentence is not auto-capitalized when the first word is followed by an apostrophe. I've tried both in english and in italian.
After a full stop, the sentence "i am happy" will be auto-corrected in "I am happy" but if you write "i'm happy", it will remain uncorrected.
Steps to Reproduce:
1.in a new document, write "i'm happy" without capitalizing the first letter with the keyboard.
The first letter remained not capitalized
it should have capitalized it
User Profile Reset: No

I also tried resetting user profile. Nothing changed.
No it works correctly if you disable the Tools -> AutoCorrect -> AutoCorrect Options: Localized Options "Single Quotes" Replace check-box.
The quotation Replace action asserts before the Capitalize actions--so the initial position gets dropped.
As noted, in this case the intitial AutoCorrect action replaces the Single Quote.
Running a second AutoCorrect pass can be done from Tools -> AutoCorrect -> Apply
Most of the AutoCorrect [M] actions apply only to paragraphs with "Default" style. So check to be sure the paragraph remains in Default style and then rerun the AutoCorrect.
The initial I will be capitalized. But needing the paragraph in Default style is a nuisance, bug 59034.
