Re: UTF-Morse
Yes, it's true. Marco had sent me his UTF-Morse proposal just yesterday, along with a suggestion that I put together an implementation for April Fool's Day. And darned if I wasn't really going to do it. As a JOKE. But Marco, you need to check your invented sequences again. The leading and trailing Morse code units for the (non-ASCII) multi-Morse characters conflict with some of the single-unit characters. For example, U+002D -- looks like a leading unit, and U+0023 .-.-.. looks like a trailing unit. (It's only a JOKE, guys.

Otto Stolz wrote: Marco, you shall be called Marcone, or even (granting a Pluralis majestatis): Marconi ;-) Hey! I have a little bit of a belly, but not yet enough to justify calling me Marcone. :-) BTW, your careful analysis of Morse needing four code units made me think that there could be a digital Morse, where each code unit takes up two bits. E.g.: 00: letter gap 01: dot 10: dash 11: word gap Up to four code units could stay in each octet. E.g., the word MORSE would become: Morse: -- --- .-. ... . Bits: 10100010 1011 10010001 01010001 Hex: 0xA2 0xA1 0x91 0x51 Wow! One octet less than ASCII! :-) _ Marco
Re: UTF-Morse
Marco Cimarosti scripsit: Wow! One octet less than ASCII! :-) Well, sure. The variable-length encoding represents a mild degree of compression, though it works best for English, being based loosely on English letter frequency statistics. But compression aside, we would expect a scheme that encodes only ~40 characters to do better than ASCII. -- Winter: MIT, John Cowan Keio, INRIA,[EMAIL PROTECTED] Issue lots of Drafts. http://www.ccil.org/~cowan So much more to understand! http://www.reutershealth.com Might simplicity return?(A tanka, or extended haiku)
