ASCII text is not a solution that works. "ASCII art" - using text characters and layout to represent graphic content - is an extremely poor choice for making graphics that can be presented to users of braille, or people using speech systems. It is about the only widely used representation of images that doesn't include the ability to have a description of the image hidden in the image, but available to software that can present it to the user, and it makes no sense translated in braille, nor when read by a screen reader, nor is it scalable, and it makes no sense in the presence of commmon text changes. ASCII only covers the characters used in a handful of languages - it is not sufficient to write French, German, Spanish, Italian, Vietnamese, Japanese, Greek, Russian, Chinese, Urdu, Arabic, Thai, Mongolian, etc. (It is possible to represent those language in ASCII, but very difficult to use and there are no standards - french and english speakers have different ways of writing the same arabic word, and english speakers have different ways of writing chinese words - whereas there are at least widely used standards for including the relevant characters in a useful way that are used in modern software). Text is not something that everyone can use. Ther are commmunities whose ability to communicate in text is very limited. Those people have traditionally found things like Flash and SVG extremely important to making information accessible. As they are trying to use more information, and make their own information more widely accessible, things like Flash being more readily transformed to other formats such as speech, or SVG providing text-based views of the information it is representing graphically, are important steps forwards. There are a number of screen readers - I know of four for Windows, and at least four free ones for Linux, and other products. Some of these things cost money (by buying the Windows system itself, which is a couple of hundred US dollars, or half the monthly housing cost for an average australian family, and perhaps less as part of a computer purchase, you get the not very powerful Narrator software). Some peopel will produce free products, some will sell their products, and some will be able to buy anything they like, others will be constrained by their employer/school/available support. At least we are moving forwards, although there is still along way to go. Just my 2c worth. chaals On Tue, 5 Mar 2002, Access Systems wrote: HTML or ASCII Text is about as basic and standard as is possible to get and it takes almost nothing to provide.
