Bijective mappings are not suitable for Unicode->EUC mapping. The ones that the Unicode Consortium had put up were merely ment to document, where the round-trip compatibility requirement charcaters came from originally and to demonstrate that round-trip compatibility is possible in principle. Unfortunatelly, lots of naive implementors used these maps in order to write bad Unicode->EUC converters that now cause trouble. Therefore Unicode declared them to be officially obsolete, as they don't want to get made responsible for the mess that some converter authors created (many of which live around Redmond). They are still looking for a helpful soul that authors a decent best-practice guide for how to implement Unicode->EUC converters. A few starting hints of what has to be taken into consideration in this not quite trivial task are described on http://www.cl.cam.ac.uk/~mgk25/unicode.html#conv Unicode has now become such a central infrastructure, that it is now up to the maintainers of legacy encoding standards to define the relationship of their respective encodings to Unicode properly. The ISO�8859 authors have already done this in their second editions, and I understand that the latest editions of the relavant JIS standards also contain official ISO 10646 cross-reference tables. > Is there a place where they are centrally maintained?
