在Haxe中使用sys.io.File.read读取文件时指定文件编码 [英] Specifing file encoding while reading a file with sys.io.File.read in Haxe

问题描述

我知道如何使用sys.io.File.read使用Haxe读取文件(比较

I know how to read a file with Haxe by using sys.io.File.read (compare Reading lines from a file in Haxe and I also know that the sys module is not available for each target). However how can I tell sys.io.File.read that my text file is encoded via a certain encoding (e.g. UTF-16, UTF-8, ISO-8859-1, ...)?

推荐答案

无法在File级别执行此操作，但是您可以在读取文件后对String进行编码/解码.例如， Utf8.encode() 会将ISO-8859-1字符串转换为一个UTF-8字符串:

There is no way to do this at File-level, but you can encode / decode the String after reading the file. For instance, Utf8.encode() will convert a ISO-8859-1 string to a UTF-8 string:

var isoString = sys.io.File.getContent("iso_file.txt");
var utf8String = haxe.Utf8.encode(isoString);
sys.io.File.saveContent("utf8_file.txt", utf8String);

标准库当前不支持UTF-16，但是它已在Haxe 4中推出.同时，您可以使用诸如 unifill 之类的库.

The standard library currently doesn't support UTF-16, but it's coming in Haxe 4. In the meantime, you can use libraries such as unifill for that.

顺便说一句，如果您不需要逐行读取文件，请

Btw, if you don't need to read a file line-by-line, File.getContent() is much more convenient than the File.read()-approach you linked.
