Hello, The report of Henrique, very accurate as usual :)
I just wanted to add two extras: - Table-making characters that mixed single-lined and double-lined borders were reused to accomodate the extra characters. That is why programs that used tables mixing single-lined and double-lined borders look awkward in most western European machines using 850/858. - IIRC, one of the characters that were reused was a single character that exists in 437 to represent the currency that existed in Spain before the Euro times, the "Peseta" (btw a Catalan-style diminutive for "Peso", which is often used in some Spanish speaking countries). It was usually abbreviated to "Pta" or "Ptas", so you get used to saving 3 or 4 characters for it in contability software. I know no computer program that ever used that single-character "Peseta" sign that existed in CP437. With the Euro € sign you no longer have that problem, but it came in 2002, well after Windows95, so I assume not many programs were actually designed for CP 858. Nevertheless, I would recommend always using CP858 if you planned to use CP850.
