JSONはUTF-8でやりとりするけど\uでエスケープ？して書くときはUTF-16でサロゲートペアになるやつはUTF-16で書く。ふむふむ理解できない…。

  JSON
  
  JSON (JavaScript Object Notation, pronounced ; also ) is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and arrays (or other serializable values). It is a common data format with diverse uses in electronic data interchange, including that of web applications with servers. JSON is a language-independent data format. It was derived from JavaScript, but many modern programming languages include code to generate and parse JSON-format data. JSON filenames use the extension .json. Douglas Crockford originally specified the JSON format in the early 2000s. He and Chip Morningstar sent the first JSON message in April 2001. Naming and pronunciation The 2017 international standard (ECMA-404 and ISO/IEC 21778:2017) specifies "Pronounced , as in 'Jason and The Argonauts'". The first (2013) edition of ECMA-404 did not address the pronunciation. The UNIX and Linux System Administration Handbook...

  @ernix 純粋なJavaScriptならUTF-16だけで幸せそうな気もするんですが、いろいろ事情があるんですかね…

  @zundan もともとJSONはRFCが改訂されるまでマルチバイト文字直は御法度じゃありませんでしたっけ。\uXXXX使わないといけなかったと記憶してます。カッコやらダフルクォートやら全部UTF-16にしてしまうとASCIIのスーパーセットにならないのでそれは避けたかったのかなと。

  @ernix あーなるほど。UTF-16の\uエスケープが先にあってそこに生のUTF-8文字が追加されたのかもしれないですね。そのうち調べたい…
