What's the difference between UTF-7 and UTF-8?
And do we have to use Unicode to send messages in languages other than English -- in order to get all the diacritics and Non-Latin alphabets? DSH Lux et Veritas et Libertas Vires et Honor |

Thank you.
What does that one bit get for you? DSH Lux et Veritas et Libertas Vires et Honor "FromTheRafters" wrote in message ... "D. Spencer Hines" wrote in message ...

Twice what you previously had. Each additional bit in binary doubles
the possibilities. One bit can describe two states, two can describe four, three can describe eight, etc... Most 7-bit systems will actually use seven bits for encoding and use the eighth bit for a parity check. This is a very simple error detection scheme in which the total number of ones in a byte are counted and the parity bit is added (or not added) to make the total odd or even in accordance with whether odd or even parity was chosen for the scheme. Any bit changed during transmission by noise would usually cause a byte to be rejected by failing the parity check. The rejected byte would have to be resent. More modern error detection schemes have the added ability to correct some errors rather than to just have the data resent. If the parity bit is not needed for error detection, then why not use it as part of the actual encoding - doubling the possibilities? "D. Spencer Hines" wrote in message ... Thank you.

Great!
Thank you kindly. So Unicode capability is essential for sending and receiving messages in many foreign languages, where ASCII just can't carry the freight.
