I suggest to use this information in a way to improve the article, without making wikipedia article any «how to use wikipedia». [[Special:Contributions/86.75.160.141|86.75.160.141]] ([[User talk:86.75.160.141|talk]]) 19:14, 11 October 2012 (UTC)

I found this article looking for why 𝓌𝒾𝓀𝒾𝓅𝓮𝒹𝒾𝒶.org seemed to land me on wikipedia.org - might be a good illustrating example. [[Special:Contributions/155.94.127.118|155.94.127.118]] ([[User talk:155.94.127.118|talk]]) 23:36, 4 September 2019 (UTC)

==Well-formedness==

"Well-formedness" refers to whether the sequences of 8-bit, 16-bit or 32-bit storage units properly define a sequence of characters (technically, 'scalar values'). Having combining characters without base characters makes a string 'defective'. There are other faults in a well-formed string that have no name, such as broken Hangul syllable blocks, characters in the wrong order (not all scripts have been set up so that canonical equivalence will 'eliminate' ambiguities), and variation selectors in the wrong places.

== External links modified ==

Hello fellow Wikipedians,

I have just added archive links to {{plural:1|one external link|1 external links}} on [[Unicode equivalence]]. Please take a moment to review [https://en.wikipedia.org/w/index.php?diff=prev&oldid=700471573 my edit]. If necessary, add {{tlx|cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{tlx|nobots|deny{{=}}InternetArchiveBot}} to keep me off the page altogether. I made the following changes:

*Added archive https://web.archive.org/20100109162824/http://forums.macosxhints.com:80/archive/index.php/t-99344.html to http://forums.macosxhints.com/archive/index.php/t-99344.html

When you have finished reviewing my changes, please set the ''checked'' parameter below to '''true''' to let others know.

{{sourcecheck|checked=false}}

== Canonicality ==

Currently the article states (under [[Unicode equivalence#Combining and precomposed characters|Combining and precomposed characters]]) that "In general, precomposed characters are defined to be canonically equivalent to the sequence of their base letter and subsequent combining diacritic marks, in whatever order these may occur", but also (under [[Unicode equivalence#Canonical ordering|Canonical ordering]]) that the canonical decomposition (of U+1EBF) U+0065 U+0302 U+0301 "is not equivalent with U+0065 U+0301 U+0302". Either this is a contradiction and should be fixed, or some further clarification would help.

== German Article ==

There seems to be a German version, which is not linked: https://de.wikipedia.org/wiki/Normalisierung_(Unicode) [[User:Skillabstinenz|Skillabstinenz]] ([[User talk:Skillabstinenz|talk]]) 20:22, 23 June 2020 (UTC)

== Naming ==

: Why do we have this article named as «'''''Unicode equivalence'''''» instead of «'''''Unicode normalization forms'''''»? It's confusing.

== A with ring above example ==

The text has:

<blockquote>For example, the distinct Unicode strings "U+212B" (the angstrom sign "Å") and "U+00C5" (the Swedish letter "Å")</blockquote>

But the two "A with ring above" characters appear to be the same Unicode character. This defeats the effectiveness of the example, for those who care to inspect the characters carefully (eg by copy-and-paste into some Unicode inspector tool). I would have to look into the article history in detail to see when these two characters were made the same.

:I didn't write the original text but have rewritten the section to clarify. Does that respond to your concern?

:I think the intention was to convey that it doesn't matter which of the two codepoints you use, since they are canonically equivalent. (Which is a face-saving way of admitting that someone boobed way back. A codepoint for angstrom sign should never have been created but what's done is done.)
