Report on Creating a Character Model for W3C Specifications

The second view is beseeming more and more important due to the following developments:

* The improver in data transfers among servers, proxies, and clients

* The summation in places where non-ASCII characters are allowed

* The increase in data transfers between different protocol/ change elements (such as element/attribute names, URI components, and textual content)

* Definition of specifications for genus Apis (as opposed to protocol specifications only) In this context, some properties of the UCS become applicable and get to to be addressed. It should be noted that such properties as well as exist in legacy encodings, and in many cases have been inherited by the UCS in one way or another from such legacy encodings. In particular, these properties are:

* quality of binary encoding forms (UTF-8, UTF-16, UCS-4) Variable length encodings (e.g. due to the put on of combining characters, surrogates,...)

* Duplicate encodings (e.g. precomposed vs. decomposed)

* Control codes for various purposes (e.g. bi-directionality control, symmetric swapping, This elbow room that in order to insure compriseent behavior on the WWW, some additional specifications, based on the UCS, are demand. This register is written as part of the work of the I18N WG to provide internationalization guideposts for the authors of W3C specifications. Because of the importance of consistent behavior for the WWW, it should be expected that the resulting guideline components w

2.5 The tie identity twin(a) specification shall be forward-compatible

2.3 The string identity matching specification shall not expose invisible encoding differences to the user.

* The XML activity, for XPointer XSL (Extensible Style Language)

1.2 Potential users of the resulting specification

Typical examples where a gap between user expectations and internal operation elicit occur in the UCS are the likeness encodings defined as canonical equivalences in [Unicode].

As an example, the UCS allows us to encode "n" both as a single code hint (U+00FC, Latin clear LETTER U WITH DIAERESIS), or as the codepoint for "u" (U+0075, LATIN SMALL LETTER U) followed by the codepoint U+0308 (COMBINING DIAERESIS). Such equivalences are artifacts of the encoding method(s) chosen for the UCS. It is expected that the canonical equivalences specified in the Unicode standard will be an excellent starting point for defining the range of things to be identified as duplicate encodings. This will make sure that the experience of the Unicode Technical perpetration with respect to character equivalences is fully leveraged. Whether any changes are necessary will have to be examined more closely. If such changes consist only of additions of equivalences, implementations of W3C specifications would collectively conform to conformance clause C9 stipulation in [Unicode, p. 3-2]: A process shall not assume that the interpretations of 2 canonical-equivalent character sequences are distinct. Additions may include some initiation forms. Another category where encoding differences are invisible to the user are the various control codes. W3C standards closelyly deal with coordinate text (as opposed to plain text). It should therefore in most cases be possible to rely on explicit markup preferably than on in-stream control codes.
