Talk:Private Use Areas

message: From WP:RfD:
*  → Apple typography -- Redirect is useless and misleading.  Only people on Macintosh computers can correctly see the title in the first place, and only people on Macs who know a fairly obscure key combination can type it.  The title is Unicode character "U+F8FF", which is in the Unicode private use area, so the appearance of the title depends entirely on what font you're using: most Mac users will see an "apple" symbol, while on my home computer, I see it as a "Euro" symbol with an extra bar.  Other people have reported seeing such things as a "no such character" box, a question mark, Klingon letters, and even the font maker's copyright statement! --Carnildo 20:24, 28 July 2005 (UTC)

message: Since all instances of this character in the document appear for me (on a Mac) as the Apple logo, it makes sense to me to have rasterized images of each version of the character. Since the character can represent a corporate logo, this raises the question of if a representation of the corresponding Unicode character constitutes fair use. --IntrigueBlue 09:25, 9 May 2006 (UTC)

replies: text: Based on further research, it would appear that the Apple logo was originally included in fonts as a copyright method, because people would not be able to redistribute the font since it contains a trademarked logo. By extension I would assume including depiction of the logo here would not constitute fair use, which kinda throws a spanner in the works. As for the other symbols mentioned, since I can't see them I can't make pictures of them either. Could somebody who can see them do this, and add the pic to the article? --IntrigueBlue 05:14, 12 May 2006 (UTC)

message: Currently, all I see on this page is this glyph: Apple over and over again.  It would be great if someone could upload the other glyphs in a similar format and insert them into the article so that others can see the correct image.  I'll add the Apple logo where appropriate.

replies: text: See the discussion above your post. What it boils down to is that the Apple logo was added as a form of copy protection, and the image you linked is listed under fair use. Use in this article would appear not to fall under blanket fair use. —INTRIGUEBLUE (talk|contribs) 01:24, 15 January 2007 (UTC)
replies: text: Fair enough.  Still, it would be nice if the other glyphs could be imaged and added to the article..PaulC/T+ 09:35, 15 January 2007 (UTC)

replies: text: Yeah, this article should basically be deleted if it doesn't make sense depending on what computer one is on. Clearly, the windows logo is not an Apple symbol.72.78.57.6 22:47, 3 October 2007 (UTC)

text: It's a trademark. You can't extend copyright with a trademark. Fair use still applies. The trademark issue is separate. Pictures of trademarked items are also fine, the key question being if the use of the trademarked image could cause market confusion. That is, could an image of the Apple logo on Wikipedia cause some fool to believe that Wikipedia is an Apple product? Since the law is not based on the theoretical maximum fool, the answer is no. Usage here is fine, no problem. Replacing the Wikipedia puzzle-globe logo with an Apple logo would of course be another matter entirely. 24.110.145.106 (talk) 06:21, 29 January 2008 (UTC)

message: See this discussion: when parsing text (eg. XML) is interesting to reduce complexity replacing tokens or tags by 1-character token, so, generates a simple text with usual characters and non-ambiguous tokens-as-characters.  This simple string can be parser by usual regular-expressions instead complex parser. 
Summarizing: the "other use" is "as reliable Unicode 1-character-token in parsing context".
Example: XML representation of multilingual text as  
  Hello, any character as 𩸽.Bye!
Now, we can reduce tagged representation to "text and token" representation, remembering the sequence of tags (eg. in an array). Let's see replacing XML-tags by "_T1_", "_T2_", etc. tokens, the  text will be _T1__T2_Hello, any character as 𩸽._T3__T4_Bye!_T5__T6... But to process the tokenized text by a regular expression the less complex is to reduce tokens to 1-character... To avoid conflict with "real text" exoctic characters (like "𩸽"), we adopt PUA as the best choice, that never conflics.  
Supposing the adoption of PUA codes 61528 (decimal) and 61527, that are the UTF-8 characters "" and "". Now we can represent the  XML text with the tokenized text and arrays (suppose JSON representation), and process its content by a simple regular expression.
{
  "content":"Hello, any character as 𩸽.Bye!",
  "open_tags":["section","p","p"],
  "attributes":[{"class":"main"},null,null],
  "close_tags":["p","p","section"],
}

message: As of Unicode 1.0.1, in the now-antiquated system of dividing the Basic Multilingual Plane into "zones", U+D800..U+DFFF were part of the O-zone, not the R-zone (which included the private use range U+E000..U+F8FF): . This was prior to U+D800..U+DFFF becoming the surrogate S-zone. So U+D800..U+DFFF seems to have been reserved space, not private use space. --HarJIT (talk) 19:51, 11 October 2021 (UTC)
