Do we have to rehash all of this stuff AGAIN? R's, John
Huh? ISO/IEC 646 IRV (another candidate for a FoPSCII precursor) replaces the ASCII $, not #, with that universal currency symbol. As for that vertical bar, sufficiently elderly practitioners of the art of Character Confusion and Coding (CCS) will recall that the ancient Earthling-Based Convention for Difficult Information Coding included two peculiar characters: a mathematical "not" sign that closely resembled Unicode's "⌐" (U+2310) and that broken vertical bar. Those characters spawned multiple wars over how they should be mapped into "ASCII" and "ISO/IEC 646" with one group arguing for caret and (solid) vertical bar, another for tilde and exclamation mark, and a third for exclamation mark and [solid] vertical bar. After much bloodshed, 16 and 32 bit character sets were invented so that almost everyone could contemplate their cakes while eating them and continued dissenters were tortured until they repented. Those battles were repeated in the development of FoPSCII when it was noticed that the 5th character of the Klingon alphabet was confusable with both the not-sign, Greek upper case Gamma, and Latin "r". In addition, the Klingon numeral 8 was easily confused with Cyrillic "Ж". This created a variant problem that the Intergalactic Consortium for Arbitrary Names and Numbers could not dismiss because of some of the advocates had a more effective means of persuasion than merely hiring lawyers. :-(
