Case folding is not done correctly when matching against the [:upper:] character class and uppercased character ranges (e.g. A-Z). Specifically, an uppercase letter fails to match against any of them when case folding is requested because plain characters in the pattern and the whole string and preemptively lowercased to handle the base case fast.
That optimization is kept and ISLOWER() is used in the [:upper:] case when case folding is requested, while matching against a character range is retried with toupper() if the character was lowercase.
