PRBool CaseInsensitiveUTF8CharsEqual	(	const char *	aLeft,

		const char **	aRightNext,
		PRBool *	aErr
	)

This function determines whether the UTF-8 sequence pointed to by aLeft is case-insensitively-equal to the UTF-8 sequence pointed to by aRight.

aLeftEnd marks the first memory location past aLeft that is not part of aLeft; aRightEnd similarly marks the end of aRight.

The function assumes that aLeft < aLeftEnd and aRight < aRightEnd.

The function stores the addresses of the next characters in the sequence into aLeftNext and aRightNext. It's up to the caller to make sure that the returned pointers are valid -- i.e. the function may return aLeftNext >= aLeftEnd or aRightNext >= aRightEnd.

If the function encounters invalid text, it sets aErr to true and returns false, possibly leaving aLeftNext and aRightNext uninitialized. If the function returns true, aErr is guaranteed to be false and both aLeftNext and aRightNext are guaranteed to be initialized.
