Correction/clarification needed to String and string documentation

TrashCompactor:
"Strings are always defined inside double quotes ("Abc") and characters are always defined inside single quotes('A')."

How can a String always be defined with double quotes but constant strings in double quotes are treated as char arrays?

They actually meant "strings are always defined inside double quotes ("Abc") and characters are always defined inside single quotes('A')." but they capitalized string in that sentence because it was the first word in the sentence, not because they were referring to a String. A string is a character array.
