Can I clarify the status of some characters of the characters Martin listed, please? > http://www.w3.org/TR/REC-xml/#charsets allows (although, at least > in never versions, discourages): > [#xFDD0-#xFDDF], > [#x1FFFE-#x1FFFF], [#x2FFFE-#x2FFFF], [#x3FFFE-#x3FFFF], > [#x4FFFE-#x4FFFF], [#x5FFFE-#x5FFFF], [#x6FFFE-#x6FFFF], > [#x7FFFE-#x7FFFF], [#x8FFFE-#x8FFFF], [#x9FFFE-#x9FFFF], > [#xAFFFE-#xAFFFF], [#xBFFFE-#xBFFFF], [#xCFFFE-#xCFFFF], > [#xDFFFE-#xDFFFF], [#xEFFFE-#xEFFFF], [#xFFFFE-#xFFFFF], > [#x10FFFE-#x10FFFF] > > In the IRI spec, these are excluded: > ucschar = %xA0-D7FF / %xF900-FDCF / %xFDF0-FFEF > / %x10000-1FFFD / %x20000-2FFFD / %x30000-3FFFD > / %x40000-4FFFD / %x50000-5FFFD / %x60000-6FFFD > / %x70000-7FFFD / %x80000-8FFFD / %x90000-9FFFD > / %xA0000-AFFFD / %xB0000-BFFFD / %xC0000-CFFFD > / %xD0000-DFFFD / %xE1000-EFFFD I see XML discourages FDD*, but the ucschar excludes both FDD* and FDE*. Does anyone know the reason for this discrepancy? FDE* seem to be also "not a character". ucschar also excludes E0***, which seem to be "tags" - what does that mean? ucschar also exclude FFF*, but XML makes no mention of them, except of course FFFE and FFFF which aren't allowed in XML at all. -- Richard
