Native code execution also requires a variety of supplementary data to describe how the code needs to be bound into a JVM and how to catch exceptions, for example, so that the code can be executed.

执行本地代码还需要各种补充数据，用以描述如何将代码绑定到JVM以及如何捕获异常(比如)，从而执行代码。

Counting code units using either CODEUNITS16 or CODEUNITS32 gives the same answer, unless supplementary characters or a surrogate pair is involved.

使用CODEUNITS16或CODEUNITS32计算代码单元得到的结果是相同的，除非使用了增补字符和代理对。

When supplementary characters are involved, a supplementary is counted as two UTF-16 code units using CODEUNITS16, or one UTF-32 code unit using CODEUNITS32.

使用增补字符时，对于一个增补字符，使用 CODEUNITS16 计算是两个 UTF-16 代码单元，而使用 CODEUNITS32 计算则是一个 UTF-32 代码单元。

The Unstructured Supplementary Service Data (USSD) code (which we won't reproduce here) apparently only works on Samsung phones running Touchwiz, and only if you are directed to the dodgy destination while inside the stock browser (rather than Chrome, for example).
