如何将文件从ASCII转换为UTF-8? [英] How to convert a file from ASCII to UTF-8?
问题描述
我正在尝试将一堆文件从ASCII转换为UTF-8.
I'm trying to transcode a bunch a files from ASCII to UTF-8.
为此，我尝试使用iconv:
iconv -f US-ASCII -t UTF-8 infile > outfile
-f ENCODING输入的编码
-t ENCODING输出的编码
仍然该文件未转换为UTF-8.这是一个.dat文件.
Still that file didn't convert to UTF-8. It is a .dat file.
在发布此信息之前，我搜索了Google并发现了以下信息:
Before posting this, I searched Google and found information like:
ASCII是UTF-8的子集，因此所有ASCII文件均已采用UTF-8编码. ASCII文件中的字节和将其编码为UTF-8"所产生的字节将完全相同.它们之间没有区别.
ASCII is a subset of UTF-8, so all ASCII files are already UTF-8 encoded. The bytes in the ASCII file and the bytes that would result from "encoding it to UTF-8" would be exactly the same bytes. There's no difference between them.
仍然上面的链接没有帮助.
Still the above links didn't help.
即使采用ASCII格式，它也将支持UTF-8，因为UTF-8是超集，要从我这里接收文件的另一方也需要将文件编码为UTF-8.他只需要UTF-8这样的文件格式即可.
Even though it is in ASCII it will support UTF-8 as UTF-8 is a super set, the other party who is going to receive the files from me need file encoding as UTF-8. He just need file format as UTF-8.
请提出任何建议.
推荐答案
这个问题让我有些困惑，因为正如您所指出的，ASCII是UTF-8的子集，因此所有ASCII文件都已经是UTF- 8个已编码.
I'm a little confused by the question, because, as you indicated, ASCII is a subset of UTF-8, so all ASCII files are already UTF-8 encoded.
如果您要向另一方发送仅包含ASCII字符的文件，但是另一方抱怨它们不是"UTF-8编码"的，那么我猜他们是在指这样的事实: ASCII文件没有字节顺序标记，明确指示内容为UTF-8.
If you're sending files containing only ASCII characters to the other party, but the other party is complaining that they're not 'UTF-8 Encoded', then I would guess that they're referring to the fact that the ASCII file has no byte order mark explicitly indicating the contents are UTF-8.
如果确实如此，则可以在此处使用答案添加字节顺序标记:
If that is indeed the case, then you can add a byte order mark using the answer here:
iconv:从Windows ANSI转换为UTF- 8，带BOM
如果另一方指示他不需要"BOM"(字节顺序标记)，但仍抱怨文件不是UTF-8，则另一种可能性是您的初始文件实际上不是ASCII，而是而是包含使用ANSI或ISO-8859-1编码的字符.
If the other party indicates that he does not need the 'BOM' (Byte Order Mark), but is still complaining that the files are not UTF-8, then another possibility is that your initial file is not actually ASCII, but rather contains characters that are encoded using ANSI or ISO-8859-1.
经过编辑，添加了以下实验，这是Ram提出的有关另一方使用文件"命令寻找类型的评论之后
Tims-MacBook-Pro:~ tjohns$ echo 'Stuff' > deleteme
Tims-MacBook-Pro:~ tjohns$ cat deleteme
Stuff
Tims-MacBook-Pro:~ tjohns$ file -I deleteme
deleteme: text/plain; charset=us-ascii
Tims-MacBook-Pro:~ tjohns$ echo -ne '\xEF\xBB\xBF' > deleteme
Tims-MacBook-Pro:~ tjohns$ echo 'Stuff' >> deleteme
Tims-MacBook-Pro:~ tjohns$ cat deleteme
Stuff
Tims-MacBook-Pro:~ tjohns$ file -I deleteme
deleteme: text/plain; charset=utf-8
