我的 HTML 页面使用<meta charset="windows-1252">.
- Is changing to
UTF-8recommended and why? - I checked some of my pages with
UTF-8and got question marks with some math symbols. E.G: x should be changed to × in order to show correctly. I tried theCpConverterbut it did not convert well all the symbols.
- 是否改为
UTF-8推荐，为什么？ - 我检查了我的一些页面
UTF-8并得到了一些数学符号的问号。EG: x 应该改为 × 才能正确显示。我试过了，CpConverter但它没有很好地转换所有符号。
Is there a better way to convert many files?
有没有更好的方法来转换许多文件？

- UTF-8is generally approved standard, which works everywhere. Windows-any encoding is Windows-specific and not guaranteed to work on any machine. Also, take a look hereand here
- If you want to change the encoding of a file, you can do it in many ways. You can look for encoding type in your text editor/IDE or use the following command (not tested, it should work though):
- UTF-8是普遍认可的标准，适用于任何地方。Windows-any 编码是特定于 Windows 的，不能保证在任何机器上都能工作。另外，看看这里和这里
- 如果要更改文件的编码，可以通过多种方式进行。您可以在文本编辑器/IDE 中查找编码类型或使用以下命令（未测试，但它应该可以工作）：
iconv -f WINDOWS-1252 -t UTF-8 filename.txt
iconv -f WINDOWS-1252 -t UTF-8 filename.txt

It's an old question but my answer may help someone to decide better.
这是一个老问题，但我的回答可能会帮助某人做出更好的决定。
Changing from ANSI(windows-1252) to UTF-8 approximately doubles the size of HTML files. (Depending on characters used in the file)
从 ANSI(windows-1252) 更改为 UTF-8 大约会使 HTML 文件的大小增加一倍。（取决于文件中使用的字符）
If you want to test this, just create a file in notepad with the following characters:
如果要对此进行测试，只需在记事本中创建一个包含以下字符的文件：
???
？？？
These characters are both in ANSI(Windows-1256) and Unicode. Save the file once with ANSI(Windows-1256) encoding and once again with UTF-8 encoding.
这些字符都是 ANSI(Windows-1256) 和 Unicode。使用 ANSI(Windows-1256) 编码保存文件一次，再使用 UTF-8 编码保存文件。
Size of the UTF-8 file: 9 bytes
UTF-8 文件的大小：9 字节
Size of the ANSI(Windows-1256) file: 3 bytes
ANSI(Windows-1256) 文件的大小：3 字节
if you want to change the charset of your page, simply open them in notepad or any other editor and save as with UTF-8 encoding.
如果您想更改页面的字符集，只需在记事本或任何其他编辑器中打开它们并使用 UTF-8 编码另存为。
