(By about a factor of 4 for primarily-ASCII text, or three or two for 2-byte and 3-byte-per-char ranges.) Your method is faster for short strings... but all are well under a millisecond on my 2.33 GHz Core Duo test box for long strings, and under a tenth of a ms for the short strings, so it perhaps gets into splitting hairs. ;) Hm, that’s clever too. :)
