如果我使用Java 8的String.codePoints来获取int codePoints数组，那么数组的长度是字符数吗？ [英] If I use Java 8's String.codePoints to get an array of int codePoints, is it true that the length of the array is the count of characters?
问题描述
在Java中给出字符串字符串， string.codePoints（）。toArray（）。length 反映了 String 的长度，就人类会发现有意义的实际字符而言？换句话说，它是否平滑转义字符和其他编码工件？
Given a String string in Java, does string.codePoints().toArray().length reflect the length of the String in terms of the actual characters that a human would find meaningful? In other words, does it smooth over escape characters and other artifacts of encoding?
编辑人类我的意思是程序员正如我想象的那样，大多数程序员会将 \\\\ n 视为两个字符， ESC 作为一个字符等但是现在我看到即使重音标记被雾化也无所谓。
Edit By "human" I kind of meant "programmer" as I would imagine most programmers would see \r\n as two characters, ESC as one character, etc. But now I see that even the accent marks get atomized so it doesn't matter.
推荐答案
没有。
例如：
-
控制字符（例如ESC， CR，NL等等不会被删除。这些在Unicode中具有不同的代码点。
Control characters (such as ESC, CR, NL, etcetera) will not be removed. These have distinct codepoints in Unicode.
空格，制表符等的序列未合并
Sequences of spaces, tabs, etc are not combined
自由连字符（ http://www.fileformat.info/info /unicode/char/00AD/index.htm ）不删除字符。
Discretionary hyphen (http://www.fileformat.info/info/unicode/char/00AD/index.htm) characters are not removed.
Unicode组合字符（ https://en.wikipedia.org/wiki/Combining_character ）未合并。
Unicode combining characters (https://en.wikipedia.org/wiki/Combining_character) are not combined.
现在有争议的是，其中一些可能是人类会发现有意义的实际角色 ...但总体答案仍然是否定。
Now it is debatable whether some of these might be "actual characters that a human would find meaningful" ... but the overall answer is still No.
您澄清如下：
通过人类我的意思是程序员，因为我想大多数程序员会将\\\\ n视为两个字符...
By "human" I kind of meant "programmer" as I would imagine most programmers would see \r\n as two characters ...
确实如此比这更复杂。我是程序员，对我来说，取决于上下文， \\\\ n 是否有意义。如果我正在阅读README文件，我的大脑会将空白区域中的差异视为没有语义重要性。但是，如果我正在编写解析器，我的代码会考虑空格...取决于它要解析的语言。
It is more complicated than that. I am a programmer, and for me it depends on the context whether \r\n are meaningful or not. If I am reading a README file, my brain will treat differences in white space as having no semantic importance. But if I am writing a parser, my code would take whitespace into account ... depending on the language it is intended to parse.
