python - 为什么 Python 在打开 utf-16 文件时不读取行尾字符？

Question

我正在连接两个文本文件，一个是 utf-16。从文件中读取行并将它们拆分时，utf-16 文件没有行尾。一切都在一行中，所以我必须指定一个行尾字符。任何想法为什么？

下面的代码正在运行，但我想知道为什么我需要为 utf-16 设置行尾。

with open(file_temp, 'w') as outfile:
    with open(file_normal) as infile:
        for line in infile:
            outfile.write(line.split(",")[0]) # auto end of line
    with open(file_utf16, encoding='utf-16') as infile: # different file format
        for line in infile:
            outfile.write(line.split(",")[0] + "\n") # needs end of line char for some reason ?

当以正确的编码读取时，我希望行尾字符出现在 utf-16 文件中。

换行符与编码无关

with open("someFile_utf16.txt", "w",encoding='utf-16') as infile:
    for x in range(10):
        infile.write(str(x))

with open("someFile_normal.txt", "w") as infile:
    for x in range(10):
        infile.write(str(x))

两者在文件中都有相同的数据

唯一可能的解释是普通文件写入了行尾，而 utf-16 文件没有
