Guessing, without having looked at the code or API involved... is the "string length" here a count of UTF-8 _bytes_, but the "rectangles" are one per _character_? If so, you'd get a discrepancy as soon as non-ASCII characters (such as bullets, curly quotes, em-dashes, accented letters, etc, etc) are present.
