All true, but only for the Web. Does not apply to ISO-2022-compliant
applications. The beauty of standard character sets is that they work for
all interchange applications, not just certain kinds.

By the way, I mentioned this once before, but just to be sure everybody is
aware: the fact that CP1252 0xA0-0xFF (GR) coincides with ISO 8859-1 does
not carry over to the other CP12xx's:

 Windows ISO GR Matches Domain
 CP1250 8859-2 No Latin-2 (East Europe Roman)
 CP1251 8859-5 No Latin/Cyrillic
 CP1252 8859-1 Yes Latin-1 (West Europe Roman)
 CP1253 8859-7 No Latin/Greek
 CP1254 8859-3? -9? No Turkish
 CP1255 8859-8 No Hebrew
 CP1256 8859-6 No Arabic
 CP1257 8859-4 No Latin-4 (Baltic)
