> Unicode email is not working properly
Wrong. It works as described.
> ISO Email is working properly.
Not more reliably than Unicode-based implementations. In fact, most email agents now process emails by first converting all 7/8-bit charsets they *know* into Unicode/ISO/IEC10646. If it works in ISO8859, it also works without change with Unicode. Implementations that do not convert first to Unicode/ISO/IEC10646 fail to handle lots of 7/8-bit encodings, and have extremely complex configurations of fonts, or are not easily extensible to support more.
> Hacked 8bit coding works among vendor opposition.
Wrong. Such hacks only works with *prior* mutual agreement, and requires specific implementations. Unicode/ISO/IEC 10646 does not require such agreement, especially for emails that use almost all modern languages that have been encoded in ISO/IEC10646. Many countries have chosen to not develop a 7/8-bit encoding because they don't need to.
> Unicode desktop publishing is virtually non existent.
> ISO desktop publishing is working excellently.
Wrong, because I think you mean ISO8859 here, and not ISO here (bad terminology from you). Such implementations fail to handle lots of characters that are supported with ISO10646. The most serious publishing softwares are now based on ISO10646 as their core working encoding, simply because fonts are made now based on it, and forget to provide tables mapping legacy charsets to the needed glyphs. To support more languages, andget consistent results the largest high-quality fonts are based on technologies like OpenType and AAT that DO require support of ISO/IEC 10646;
> Hacked 8bit coding work very well in desktop publishing.
Wrong. Such documents are not portable without the complete set of applications and tuning parameters that make up an environment. Due to licencing problems, such complete sets cannot be exchanged freely, and so documents created by users cannot be worked with others; this causes problems between publishers and authors, because authors will not want to invest the money to match exactly the environment of the publisher.
Hacked encodings are also poorly encoded, and if doucmentation is available, it will be available only in one or a few languages, with poor translations, and with little people ready to help to work on these documentation. Unicode and ISO/IEC 10646 competence is available worldwide, and at very low cost. Authors and publishers can also choose the tools they want, and they have plenty of solutions.
Remember that before desktop publishing, the main work is performed by authors that simply use word processors or common database or spreadsheet office tools. All serious publishers know how to handle the format used in submissions by authors.
Remeber also that today, the work of a publisher is not only to print the documents, but also to prepare them for publication on other medias. Publishing on the Internet, or on CDROMs or making them accessible through databases is a great way to increase the audience of those documents, that can then get a newer public, and so a higher value; this benefits to authors (I don't speak here about the protection of medias, this is a separate issue and a separate choice by authors and publishers, where the encoding of texts has absolutely no influence).
> Collation (after 15 years) is not yet working in Unicode.
Huh???? Completely wrong.
> ISO collation works very well.
Very well? Not sure. Not better than collation based on Unicode/ISO/IEC 10646; the results are identical and do not depend on the encoding of the documents. In fact, implementations based on unicode perform better, because they don't need special hacks like in 7/8-bit encodings to handle characters present in one document using one encoding, but absent from another.
If you are speaking about the binary ordering, this is not collation, and there exists *NO* 7-8bit encoding whose binary encoding supports the conventions used in different languages. To suppport many languages the issue is *not* in the encoding of documents, but in the rules specific to each locale which are *completely* independant of the encoding.
> Hacked 8bit coding not known to support collation.
Wrong. There are Unicode-based implementations that have the support allwoing users to create simple custom mappings for "hacked" 8-bit encodings to Unicode. With those mappings, collation works immediately, based on existing rules for many languages.
> Unicode word processing works with few vendor applications with immense
There's no difficulty today. There are plenty of implementations everywhere, either in wellknown commercial Office applications, or in free open-source applications which can be supported by a wide range of service providers (with contract) or by the community of users (but without guarantee of service, in terms of delay, and without obligation by anyone in the community to reply to those that would insult them, like you did here!)
> ISO word processing woks perfectly with mostly all applications.
Not always (note your repeated terminoloy error: I suppose you mean ISO8859 or ISO646 here, but not ISO10646...). There are plenty of word pressing applications that support only a few (if not only one!) ISO 8859 encoding.
> Hacked 8bit works with applications, unless OS vendors deliberately prevent
Wrong. Many applications provide absolutely no way to specify that a hacked encoding is used, so they cannot guarantee consistant results (so conversion of case, hyphenation, word breaking, line breaking, and so on will not work appropriately, as the origin encoding had distinct properties for the characters before they were hacked).
To get consistant results would mean that the hacked positions can only be replaced by characters having ALL the same properties. In practice, this is imppossible to achive for complete alphabets, or for non-alphabetic scripts (just look at indic abugidas, or right-to-left scripts, or ideographic scripts, or syllabaries, and you'll see that it's impossoble to create a "hacked font" that will support them and will map characters with the same properties as with the non-hacked font.
> Standardising the encoding is not to do with interoperability of languages.
Hmmm... this sentence has no sense.
Languages by definition are not interoperable, and each have their own semantics with no exact equivalence. But in fact, every humane language is not completely unified, and are in fact families of cultures with differences across regions, social groups, and people (and their own experienceof the language).
> Inter operability is a welcome by product.
This sentence has no meaning.
> Unicode is designed primarily of interoperability as the target.
Not alone! In fact this is Unicode, along with ISO/IEC 10646 and the adoption of a common terminology and reference by OS and software vendors, and by ISO and almost all other standard bodies in the world (public or private), to base other protocols on it, or to adapt all existing protocols to support it each time it was possible (notably when the old protocol already allowed specifiying several legacy 7/8-bit encodings, using encosing identifiers like in MIME, in the IANA registry or in Internet protocols, or some other identiers like the CCSID in IBM platforms, or the codepage numbers in Microsoft and some IBM platforms.)
> It lost it first hurdle in definition.
Nothing demonstrated here. This sentence has a too broad meaning to be usable or attested by enough convincing facts. This just looks like a flaming attack.
