PUA (Unicode)

[22] Unicode私用域 (private use area) は、 Unicode Standard で特定の意味が規定されず、 利用者等が用途を定めることができる符号位置群です。


[7] 他の文字コードとの変換表で対応関係が規定されている場合、 実装者が内部的に用いる場合、 実装者が規定して利用者に提供する場合、 フォントが規定して利用者に提供する場合、 利用者が自ら規定して用いる場合があります。

[12] その性質上、相互運用性はまったく期待できません。 書き捨ての文書など例外的な場合を除き、使うべきではありません。 また他の誰がどのような用途で用いているかわかりませんから、 内部処理用にも使うべきではありません。


[23] Unicode 以前の文字コードやその実装にも、 外字EUDC自由領域といった呼称で同様の符号位置ビット組合せが用意されていたり、 空き領域を実装が勝手に使ったりしていました。

As the proposal for VietThai script to the Unicode is still in progress, we use the Private Use Area for VietThai characters (U+F000..U+F07E). A VietThai font encoded accordingly is also available in the package.

[20] Basic message formatting | Slack (Slack著, ) https://api.slack.com/docs/message-formatting

The Slack message server and API handle conversion from several binary emoji formats - the Unicode Unified format (used by OSX 10.7+ and iOS 6+), the Softbank format (used by iOS 5) and the Google format (used by some Android devices). These Unicode code points will be converted into their colon-format equivalents.

The content of a string is copied across. Escaped characters are transformed as necessary; characters and escapes that have no equivalent XML character (\b, \f, and characters of the form \uxxxx less than \u0020, except for \u0009, \u000A, and \u000D) are transformed by adding \uE000 to them.

[35] Character Description Language - Wenlin Guide () http://guide.wenlininstitute.org/wenlin4.3/Character_Description_Language

Wenlin Variation Sequences depend on Wenlin CDL font support: Wenlin uses a whole plane of Private-Use Area (PUA) characters (U+F0000..U+FFFFD), to define its own Private-Use Variation Selectors (PVS). Wenlin uses these PVS to define Wenlin’s own Private Variation Sequences, used to manage glyph variation in the CDL Database.
